As used herein, the terms "wavelength,", "band", "absorption band," or ''spectrum 200949832' refers to the optical frequency, radiation, and/or absorption value obtained from the value ±3〇 Nai' m. For example, the 405 nm band includes waves ranging from 375 nm to 435 nm. The 650 nm band includes wavelengths ranging from 620 nm to 680 nm. Defined by the wavelengths. In one embodiment, a first wavelength of the particular wavelengths is used to write data and a second wavelength of the particular wavelengths that are at least 200 nanometers from the first wavelength is used Reading the data. In another embodiment, the particular wavelength is used to write the data and read the data. The color can be used to refer to the wavelengths used for the media and systems. For example, using the 4 still nano "blue light "The band is written to the media and uses the 650 nm 'red" band to read the media. The media may be referred to as "Read Blue Read Red". ". As used herein, the term "contrast agent" is defined as any material that, when combined with an absorbent, can produce a contrast within the band to be read due to physical or chemical changes. The contrast agent can be a leuco dye, A combination of a leuco dye and a developer/developer precursor, or a change in the number of (4) (8), a change in the refractive index (8), a change in the reflectance (7), and a change in the coating size (for example, thickness).

The dual and single optical data recording medium (shown in Figures 1 and 2) disclosed herein can be used to record optical data or visual images, and then when transmitted to a beam of a predetermined wavelength, it can be transmitted and read. pattern. The system for writing and/or purchasing this special data is shown in Figure 1 and includes an optical element 148, a source 150 that produces an incident energy beam 152, and a beam that can be picked up by the pick-up 157. 154, and a transmission beam 156. In the form of a transmissive optical disc, the transmitted beam 156 is detected via a lens or optical system 6 by means of a detector 158 (which is a non-limiting example of a photodetector) and also analyzes the presence of a signal agent. It should be understood that Fig. 2 is a schematic block diagram showing a portion of the read/write system 170 of the same optical component shown in Fig. 1. In some embodiments, the system 17 includes a source 15 that emits the write wavelengths when necessary and can emit the read wavelengths when necessary. In other embodiments, the system 170 includes a light source i5 that can emit a write wavelength and a different light source (not shown) that can emit a read wavelength. These different writing and reading sources are particularly suitable for dual wavelength optical media. Figure 1 also shows the controller 164 of the rotation of the motor 162 and the material (4) of the optical disc/imaging medium 100. A mark (group) that can be read/detected by an optical sensor (e.g., fresh pickup 157) (indicated by 242 in Fig. 2). The position of the sensor (e.g., optical pickup 157) can be at least one readable pattern of the optically detectable indicia (group) 242 of the imaging medium (10). Typically, the sensor can read at least one readable pattern as the imaging medium 100 moves with the sensor. The laser beam of the sensor is concentrated in the marked surface and the change in the reflected beam can be recorded. The sensor can transmit a readable pattern in the form of one or more signals to the processor 166.

The processor 166 and the analyzer 168 can be mounted together or otherwise to handle the back beam 154 of the signal 165 from the pickup 157 to the processor 166 and to process the signal transmitted from the photodetector 58 163 and a transmission beam 156 associated with the transmissive disc format. A display 114 is also provided to display the results of the processing (which is typically in the form of a material). The system can also include such processed/analyzed data that can be collected and stored for subsequent correction. Figure 2 is a block diagram showing the read/write system 170 illustrating a portion of the same optical component shown in Figure 1. More specifically, Figure 2 illustrates the read/write system 17A applied to the imaging medium 1 施. The single and dual wavelength imaging media 100 includes a substrate 22 and a marking layer (i.e., a marking coating) 23 on its surface 222. In the illustrated embodiment, imaging medium 100 further includes a protective layer 235, such as a conventional protective layer. However, it should be understood that other embodiments of the imaging media include; such protective layer 235 is included.隹Green developer and colorless a VTTT & ¥ material is dissolved in it to better prevent each component from prematurely combining and producing optical changes throughout the mark; It can be achieved by incorporating the species of the contrast agent 24G into the target 23〇 as the precursor of the component. In these embodiments, the incident light or heat can be chemically altered in the financial device (4) to make it into the desired group 9 200949832 parts. Once the desired component is formed, the two components can be present locally and a contrast-forming reaction occurs. Thus, an optically detectable mark 242 can be created if the energy of the write human wavelength is applied to the desired area of the mark layer 230. In this application, this is achieved by using a developer precursor that is in close proximity to the dye in the marking layer 23〇. The photographic agent does not have activity as a developer unless the developer precursor has been absorbed to cause it to be chemically rearranged. Thus, the developer precursor can also function as the absorbing agent 239. After the rearrangement, it can act as a developer when it comes into contact with the dye. Thus, the use of the developer precursor prevents the color formation/contrast reaction from occurring before the pure, (10) ambient material τ, which may be provided in the form of a homogeneous, single phase solution. - However, in other conditions, under ambient conditions, one or the other of the components may be substantially insoluble in the matrix. "Substantially insoluble" means that under the ring member, the solubility of the contact with _2 at the base (4) is such as =' that the reaction of the dye with the display is observed under ambient conditions. Thus, in certain embodiments, under the ring = component, the development is dissolved in „ and the dyed _ is present in the small crystals suspended in the shell; however, in other implementations, the environmental conditions are small Dissolved in the matrix with the development _ suspended in the matrix, the day of existence, the particle size is preferably less than 150 nm. Next, the selected contrast agent (10) ... when activated, at the desired wavelength = record The material may have more or less sputum. The single-wavelength of the light used for reading and writing may generally cause the contrast agent 24q to be generated for writing at the same wavelength or within the same wavelength range for reading. Dark 200949832 (relative to the unmarked area) mark 242. In many cases (which includes reading and writing in the 405 nm band as described using the single wavelength system), preferably and most It is preferred to provide a contrast agent 24 〇 which, when exposed to a relatively narrow range of wavelengths, can be produced with a relatively absorptive mark 242 for the same relatively narrow wavelength range for reading. Furthermore, the applicant of the present invention has improved this example. In some instances 'the contrast agent 24 More functionality of 0 is desirable. When the data or image is to be read at the same wavelength used for writing (ie, its energy can cause the physical and/or chemical changes of the contrast agent 240), the reading The extraction process can alter the results of the writing process, and the applicant of the present invention has discovered the advantage of using an absorbable absorbent 242 suitable for writing purposes in a first wavelength band (e.g., from 380 nm to 420 nm). A contrast agent 240 is generated that produces an optically detectable indicia 242 that absorbs light (and is therefore readable) at a wavelength that is at least 200 nanometers from the writing wavelength. Such read band wavelengths can be as high as 650 nm or 780 nm or 900 nm. Therefore, when reading such data or images, it is not intended for use in writing processes that can cause changes in contrast agent 240. The same optical wavelength is read. Therefore, the chance of the reading process changing the result of the writing process can be substantially minimized or can be eliminated by using the dual wavelength system. When writing high precision data, Particularly useful and important. Generally believed Writes and reads at different wavelengths provide better control and higher range for data writing and picking. Some of these systems and methods are characterized by optical contrast that does not dissipate and excellent data storage. Capacity. When the symbol 242 is to be created, the marking energy U〇 is concentrated in the desired manner 11 200949832 to the imaging medium 100. The form of the energy may vary depending on the equipment used, the environmental conditions, and the desired result. Examples include, but are not limited to, infrared (IR) radiation, ultraviolet (UV) radiation, X-rays, or visible light. In these embodiments, the position of the image forming medium 230 to be illuminated with light having a desired predetermined wavelength is formed. The absorbent 239 in the marking layer 230 absorbs energy 'causing the contrast agent 240 to undergo physical and/or chemical changes to form the optically detectable indicia 242. It should be understood that the formed mark 242 can be detected by a light sensor. It will be appreciated that the particular materials and/or concentrations or ratios of materials selected for the absorbent 239 and contrast agent 240 may form the single wavelength system or dual wavelength system. It is common to say that when the single-wavelength recording medium 100 is formed, the absorbent 239 having high absorbency at a desired wavelength and the contrast agent 240 exhibiting the lowest absorbance at a desired wavelength are used. As used herein, the "lowest absorbency" component refers to a component having a maximum absorbance at any wavelength between 200 nm and 900 nm (U, having a absorbance of less than 20% at a particular wavelength). For example, CIBA's® IRGAPHOR® 1699 has absorbance at 650 nm and has the lowest absorbance at 405 nm. Similarly, the 'highly absorbable' component has the highest absorbency at the wavelength. A component having an extinction coefficient of more than 10,000. For example, CJ solvent yellow 93 is a strong dye which is highly absorptive under the 405 nm band and has an extinction coefficient of more than 50,000. When forming a dual wavelength recording medium 1 When 〇〇 is selected, it is selected for the absorbable absorbent 239 at the writing wavelength, and after being physically or chemically changed in response to the energy obtained from the absorbent 239, the absorbable contrast at the read wavelength 12 200949832 Agent 240. As a non-limiting example of the dual wavelength system, a mixture of irgaphOR® 1699 and Yellow 93 in a ratio of 9.1 is sufficient to produce sensitivity at 405 nm suitable for writing and has a sensitivity at 650 nm. good A good readable coating. As previously described, the absorbent 239 in the marking layer 230 can absorb energy and transfer energy in the layer 230 to the contrast agent 24. The transferred energy can be in the contrast agent 240. Initiating a chemical or physical change. In some instances, the energy can cause the developer precursor to be converted to a developer and activate the leuco dye. In other examples, the energy can cause the contrast agent 240 to change in absorption coefficient, change in refractive index, A change in reflectance, a change in size (e.g., thickness), or a distortion. The activation or change (group) can produce an optically detectable indicia 242 that can be in the resulting color, color change, and/or contrast of the layer 230. The form of the change is displayed. Thus, if energy is applied to the desired area of the marking layer 230, an optically detectable mark 242 can be produced.

Examples of such commercially available dyes include dyes for conventional DVD or CD recording, such as IRGAPHOR® Ultragreen MX, IRGAPHOR® LASERVIOLET, IRGAPHOR 1699 (all of which are commercially available from Ciba, Tarrytown, NY). Additional examples of contrast agents 240 suitable for the single and dual wavelength systems include the following: 1) contrast agents described in the following patents: U.S. Patent No. 5,079,135, Japanese Patent No. 2,910,042 62, European Patent No. 0376327 B1, and Hong Kong Patent No. 1007621 A1, the benefit of each of which is incorporated herein by reference in its entirety by reference in its entirety in the the the the the the the the the the the the the the the The Japanese Patent Application Publication No. 2002-002112, the entire disclosure of which is incorporated herein by reference. 25 200949832 In a non-limiting example of a dual wavelength recording medium 100 disclosed herein, the markable coating 230 can include a combination of the leuco dye Noveon Specialty Cyan 39 as the contrast agent 240 and the CI solvent yellow 93 as the absorbent 239. . Such markable coating 230 may also include suitable developers such as zinc laurate, and PERGAFAST® 201 (available from Ciba). Another non-limiting example of the dual wavelength markable coating 230, as previously described, includes C.I. Solvent Yellow 93 as the absorbent 239, and IRGAPHOR® 1699 as the contrast agent 240.

A combination of contrast agents 240. The ratios and selections of these components are configured to be written and read at 405 nm. As a non-limiting example, a 丨:9 ratio of absorbent 239 can be used as the absorbent 239: from Few Chemicals Gmbh,

Germany), and a solution of IRGAPHOR® Ultragreen MX as a contrast agent to form a medium that can be written under the 405 nm band and read under a 4〇5 nm band. © A radiation source (e.g., a laser or LED) capable of emitting blue and blue light wavelengths ranging from about 375 nm to about 435 nm can be used to form the color _ or contrast-forming composition. Thus, the color _ or contrast can be selected to form a composition for use in a device capable of emitting wavelengths within the range. In more detail, radiation sources, such as those used in certain DVD and laser disk recording devices, can emit energy at a wavelength of about 405 nm. A radiation absorber that can be modulated to the particular wavelength can be included to enhance localized heating. 26 200949832 In the embodiments disclosed herein, the matrix material can be any composition suitable for dissolving and/or dispersing absorbent 239 and contrast agent 240. Suitable matrix materials include, but are not limited to, ultraviolet curable matrices such as acrylate derivatives, oligomers and monomers, and may or may not have a ph〇t〇 package. The optical package may include a light absorbing species capable of initiating a reaction that hardens the substrate, such as a diphenyl ketone derivative. Other examples of photoinitiators suitable for free radical polymerization monomers and prepolymers include, but are not limited to, 9-oxo sulfur thioxanethone derivatives, onion derivatives, acetophenone and benzoin (benzoin) ether type. It is preferred to use a matrix which can be hardened by radiation type which is not used for writing. The base of the cationic polymerization resin may require an aromatic diazonium salt, an aromatic halogen halide salt, Aromatic sulfonium salts and metallocene compounds are mainly photoinitiators. Examples of suitable substrates include Nor-Cote CLCDG-1250A or Nor-Cote CDG000 (a mixture of UV curable acrylate monomers and merging polymers), which contains Photoinitiator (base copper) and organic solvent acrylic acid vinegar (such as methacrylate methacrylate, hexyl methacrylate, /3-phenoxy propyl acrylate, and hexamethylene acrylate) Other suitable matrices include acrylated polyester oligomers such as CN292, CN293, CN294, SR351 (trimethoprimic triacrylate), SR395 (isodecyl acrylate), and SR256 from Sartomer Co. (2(2-ethoxyethoxy)ethyl acrylate) In some instances, when the temperature of the solid substrate is below its glass transition temperature, the photochemical and/or photothermal mechanism of the developer precursor can be reduced to a much lower level. Do not agree with a particular theory, in solids. The photochemical reactions have an additional energy barrier that can heat the substrate above its glass transition temperature of 27 200949832 (Tg). Thus, in some embodiments it is preferred to provide sufficient photothermal energy in the region of the desired mark 242. The base f is locally heated to its glass transition temperature Tg. The Tg is typically dependent on the polymer composition of the substrate and, if necessary, may be selected by the polymer selected for the substrate. In certain embodiments, the Tg ranges from about 12 (TC to about 25 (TC.) The imaging composition formed by the methods described herein can be applied to a magnetic disk, such as CD, DVD, HD-DVD, BLU-RAY magnetic The surface of the disc or the like. A non-limiting example of the imaging medium 100 disclosed herein may be referred to as a "Wdte Blue-Read Red" disc, which can record data under the 405 nm band and is at 650 nm band. The data recorded on it can be read. Moreover, the magnetic disks that can be used in the systems disclosed herein include optical recording and/or reading capabilities. These systems typically include a laser (e.g., light source 150) that can emit light having a predetermined wavelength and power, including optical reading. The system for taking capacity further includes an optical pickup device 157 coupled to the laser. Laser and optical pickups are known in the art. Referring explicitly to Figures 1 and 2, representative reading The /writing system 170 includes a processor 166, one or more lasers 150 (suitable for transmitting write and/or read wavelengths), and an optical pickup 157. Signal 163 from processor 166 can cause laser 150 to emit light at the desired amount of power. The reflected light 165 from the surface of the imaging medium 100 is detected by the pickup 157, which in turn sends the corresponding signal 165 back to the processor 166. When desired to be recorded, the position of the imaging medium 1 可 causes the light emitted by the laser 150 (which has a wavelength ranging from 375 nm to 435 nm) to be projected on the marking layer 230. The laser 150 is operated such that light projected onto the marking layer 230 can transfer sufficient energy to the surface to create a mark. The position of the laser 28 200949832 150 and the imaging medium loo is controlled by the processor 166 such that light emitted by the laser 150 in the pulse can form a pattern of indicia 242 on the surface of the imaging medium 1 . At least in part, depending on the material and concentration selected for the absorbent 239 and the contrast agent 240, the mark 242 can be read at the writing wavelength (eg, 4 〇 5 nm) or at a wavelength of 200 nm from the writing wavelength. The pattern. When the pattern of indicia 242 on the surface of the imaging medium 1 is to be read, the position of the imaging medium 100 can also cause light to be emitted by the laser 15 (in some embodiments, having a range from 620) Nanometers to wavelengths of 680 nm, and in other embodiments, have wavelengths ranging from 375 nm to 435 nm) are projected onto the marked surface. The laser 15 is operated so that light projected onto the surface does not transfer enough energy to generate the mark 242 to the surface. Conversely, the incident light that is more or less reflected from the marked surface depends on the presence or absence of the mark 242. As the imaging medium moves, the change in reflectance is recorded by an optical pickup 157 that produces a signal 165 corresponding to the marked surface. The location of the laser 15 and imaging medium 100 is controlled by processor 166 during the reading process. It should be understood that the read/write system 17 described herein is merely a representative example and includes elements known in the art. Various modifications can be made including the use of multiple lasers, processors, and/or pickups, and the use of light having different wavelengths. The read elements can be separated from the write elements or can be combined in a single device. In order to further clarify the embodiments (groups) of the present disclosure, an example is provided herein. It should be understood that the present examples are for purposes of illustration and should not be construed as limiting the scope of the disclosed embodiments. 29 200949832 Example - Dual Wavelength System Sections 3-5 illustrate the use of DVDR dyes (also known as red light absorbing dyes) as contrast agent 240 in a dual wavelength system as disclosed herein, which has the same name as the conventional Write Red-Read Red The concept of the advantages of the media. The recorded blue laser spot diameter is significantly smaller than the red spot in the conventional DVDR drive. This difference in diameter during recording increases the intensity of the laser energy within the dye. Therefore, compared to the 658 nm laser, the use of a 405 nm laser 'requires relatively low laser power to record data (see Figures 3 and 4) can reduce the crosstalk (between tracks) of recorded data and The comparison (modulation) of the 405 nm blue laser recording data is significantly greater than that of the 658 nm red laser recording (see Figure 3). The read stability of the data recorded by the blue light 405 nm laser is significantly better than the read stability of the data recorded by the standard red light 658 nanometer laser (see Figure 5). Generally speaking, Media-on-Demand (MOD) can benefit from the dual-wavelength system disclosed in the text. It is better to use a secure copy-protection method to deliver media content via the Internet. It is especially important for MOD applications. For recording, as far as possible, a disk that is produced in the form of a DVD-ROM. In more detail, it is difficult to use a Push-Pull and a Wobble signal in terms of the compatibility of the old device. 65 〇n.). Compared to standard DVDR media, Blu-ray laser recording improves the performance margin (as shown in the figures), thus manipulating the trench and coating structure to specifically adjust for M ^D fine-demand disk. Example ^ can significantly reduce the push-pull and amplitude of these dual-wavelength media and can retain other major parameters such as reflectance, modulation and jitter specifications (such as Figure 30 200949832 shows that it is generally believed that the disk structure in combination with the hard encryption code can only perform blue laser writing and has excellent compatibility for DVD reading, so the pair is in DVD-ROM format. Blue laser writing of wavelength media can be mentioned An excellent choice for MOD applications. By encrypting one of the function keys in the dual-wavelength media, the content provider can substantially ensure security and copy protection without any incompatibility. And coated on the optical disc substrate. One of the compositions includes 1.5% of the conventional dye (IRGAPHOR® 1699) which absorbs in the red wavelength, and the other composition includes 丨5% containing the red wavelength absorption. A combination of a conventional dye (IRGAPHOR® 1699) and an absorbent having a bismuth absorption at a blue light wavelength (CI Solvent Yellow 93' which accounts for 1% by weight of the combination). The optical disks are exposed to 405 nm. Focus on blue-light green lasers, operating at 10wM and Sjm'GJxDVD) speeds. Data is recorded on the discs using a conventional DVD writing strategy. As shown in Fig. 6, the composition containing the absorbent has a much larger absorbance at 405 nm than the composition without the absorbent. Although several embodiments are described in detail, those skilled in the art will appreciate that the disclosed embodiments may be modified. Therefore, the above description should be considered as representative and not limiting.
