Description

• 200538454 IX. Description of the invention: [Technical field to which the invention belongs] The present invention relates to optical data storage benefits containing metal complexes in the information layer, its manufacturing method, the metal complexes present in it, its preparation, and also about Coordination group based on metal complex and preparation method thereof. [Prior art] I A write-once optical data carrier using a special light absorbing substance or a mixture thereof is particularly suitable for blue laser diodes (especially GaN or SHG laser diodes (360-460 nm)) Operating high-density writable optical data storage. 'Recently' single-write optical discs (CD-R, 780 nm) have undergone substantial growth and represent a technically established system. The next generation of optical data storage-DVDs-is now being introduced to the market. By using shorter-wave laser radiation (635_660 nm) and higher numerical aperture φ NA, the storage density can be increased. In this case, the writable format is DVD-R (DVD_R, DVD + R). Currently, a blue laser diode with high laser power (based on GaN, Japanese patent Jp 〇 8 191 171 or Optical data storage format of bismuth cdnd over generations SHG jp 0090095629 (36nm_46nm). Therefore, writable optical data storage will also be available for this generation. The achievable storage density depends on the focus of the laser point on the information plane. The spot size is commensurate with the laser wavelength λ / NA. NA is the numerical value of the objective lens used -200538454 t aperture. To obtain the highest possible storage density, use the smallest possible wavelength target. Currently, 39nm is possible based on semiconductor laser diodes. The patent literature discloses a writable optical data storage device based on a dye, which is also applicable to CD-R and DVD-R systems (Japanese Patent Jp: ii 〇43 481 and jp_A 10 181 206). In order to obtain the high reflectivity and high modulation height of the read signal and sufficient sensitivity when writing, the fact that the 78-nm φ-meter IR wavelength of the CD-Rs is located at the bottom of the long wavelength side of the dye absorption peak The wavelength of 635 nanometers or 650 nanometers of dvdRs is at the bottom of the short wavelength side of the dye absorption peak. In, for example, WO-A09 917 284 and US patent us_A52 ^ 699, this concept extends to the 45 nm working wavelength region on the short wavelength side, and the red and IR regions on the long wavelength side of the absorption peak. WO-A 03/063151 likewise discloses dyes for blue lasers. / In addition to the above optical properties, the writable information layer containing the light-absorbing organic substance f must have a substantially amorphous form in order to make the noise for writing or reading as small as possible. For this reason, it is particularly preferred that by spinning from solution = deposition and / or sublimation (continued under reduced pressure = two coatings of this substance 'to avoid the crystallization of light-absorbing substances, flying "during the electric layer) contains The non-crystalline layer of the light absorbing substance is preferably highly heat-resistant and saturable. Due to the organic or inorganic material layer applied to the light absorbing layer by impurity or vapor deposition, it will form a difficult to distinguish boundary (from & therefore) , Which adversely affects anticipation. Moreover, the first use of the edge: the mass can diffuse to the latter at the boundary of the polymeric carrier: at the same time again; no == 8.200538454 The light absorbing substance with a vapor pressure that is too high can be in another ash (in high vacuum, by sputtering or The thickness of the second sublimation period of vapor deposition is lower than the required value. This also has a negative effect on the reflectivity. [Abstract] Therefore, the purpose of the present invention is to provide information on beans and high demand. (E.g. light stability, suitable signal, compound coating on substrate material, etc.) 'is used for single-write ^ material load 2 damage (for information layer data of laser wavelength range 360 to 460) Storage format). The numerical aperture of the objective lens is preferably large, = and writable optics is preferably greater than or equal to 0.70, very particularly preferably greater than or equal to 80. At 0,60 'it was surprisingly found that it was selected from ㈣ The special metal complex composition absorbing compound can meet the above-mentioned demand profile particularly successfully. The present invention therefore proposes an optical data carrier comprising a relatively plate, which can be coated in advance if necessary-or multiple reflective layers And / or protective layer, and = • surface has been coated-light can The information layer, if necessary one or more reflective layers, and the necessary two protective layers or-additional substrates or-cover layers, which can be made of blue light, preferably with a wavelength range of 360-460 nm, especially 39.

Example 7 A solution of 3% strength (by weight) from the dye of Example 1 in 2J, 3,3-tetrafluoropropanol was prepared at room temperature. This solution was applied to a pre-grooved polycarbonate substrate by spin coating. The prefabricated grooved polycarbonate substrate has been formed into a disc having a diameter of 12 cm and a thickness of 0.6 mm by injection molding, and the gauge of the groove structure is 740 nm. By vapor deposition, a disc with a dye layer as an information carrier is coated with 100 nanometers of silver. A hardenable acrylic coating composition was then applied by spin coating, and a second identical polycarbonate 95 200538454 substrate was placed on top. The acrylic coating composition was evenly distributed over the surface of the disc by further rotation and then hardening by a vv lamp. A dynamic writing test device (including a polarized laser (λ = 405 nm) for generating linearly polarized light), a polarization-sensitive beam splitter, a χ / 4 plate, and The numerical aperture NA = 0.65 movable suspension light-collecting lens (transmission lens)) was used for writing and reading tests. The light reflected from the reflective layer of the disc is taken out of the optical path through the polarization-sensitive spectroscope described above, and focused on a four-quadrant picker by a astigmatism lens. At a linear velocity of ν = 3.5 meters / second and a write power of pwrite = 8.5 &gt; milliwatts, the signal-to-noise ratio c / N for the 11T groove was measured at 38 decibels (dB). The writing power is applied with the oscillating pulse wave sequence (please refer to the figure, in which the disc is irradiated with the above writing power Pwrite and reading power Pread «1.9 milliwatts alternately. The writing pulse wave sequence for the ιτ groove includes Length Tωρ = 15T = 60 nanoseconds leading pulse, where T = 40 nanoseconds is the base time (ιττ = 440 nanoseconds). Configure the leading pulse so that it ends after 3T units. Next is the length Tmp = 30 nanoseconds of 8 pulses, of which the time is determined by Tmp = 0.75T. Therefore, the time interval ΔΤ = 10 nanoseconds remains idle between each pair of write pulses. Ht long • write pulse The wave is followed by a 11T long pause. The disc is irradiated with this oscillating pulse wave sequence until it rotates once. Then the read power Pread is used to read the mark generated in this way, and the above signal / noise ratio C / N is measured. Similar results can be obtained using metal complexes from other examples described above.
