Description of the invention: [Technical field to which the invention pertains] / The present invention relates to a record carrier comprising a servo track, the servo track jVi ±\z —, and the information track for recording information blocks. The servo module has physical parameters for knowing the frequency change of the pre-frequency and a modulation portion for the '' flat code position information at regular intervals, and the modulation portion includes a bit synchronization element, a block synchronization element or a data bit. At least one of the elements, the elements being modulated according to a periodic variation of the same predetermined type. The invention further relates to a recording and/or playback apparatus comprising means for writing and/or reading information blocks in an information track of a record carrier, the record carrier comprising servo tracks for indicating information tracks, The apparatus includes a component for scanning a servo track, and a demodulation component for extracting position information from a signal generated by a physical parameter of the servo track that varies according to a predetermined frequency period, the servo track Having a modulation portion for encoding location information at regular intervals, the modulation portion including at least one of a bit synchronization element, a block synchronization element, or a data bit element, the elements being according to a cycle of the same predetermined type Change the modulation to adjust. The invention further relates to a method of making a record carrier. [Prior Art] A record carrier and apparatus for reading and/or writing information is known from the patent WO 0〇/43996 (ΡΗΝ 17323). The information to be recorded is encoded into an information signal containing an address code and subdivided into information blocks according to the address code. The record carrier is a type of record, and has a feed track, commonly referred to as a pregroove, which is used to scan the track, causing a servo signal to be generated at 80928-960528.doc 1310551. The physical parameters of the pre-existing (e.g., radial position) periodically change with a predetermined frequency that constitutes a so-called wobble. This swing during the scan track causes a change in the servo signal to the track and can generate a wobble signal. The wobble is modulated according to a modulation that uses phase modulation of the encoded position information. The phase modulation or frequency modulation used to encode the digital position information is selected, thereby minimizing the component of the predetermined frequency in the wobble signal because the component is used to control the recording speed. Therefore, most of the periodic changes must be unmodulated, that is, zero crossings are required and not offset from the nominal position. During the recording period, the position information is extracted from the wobble signal, and the position information is used to locate the position of the information block by maintaining a predetermined relationship between the address code and the position information in the information block. The address is encoded in the modulated portion of the wobble, starting with the bit sync element, followed by the block sync element or the data bit element. The problem with known systems is that the detection of various elements is unreliable. SUMMARY OF THE INVENTION The object of the present invention is to provide a more reliable record carrier and a device that is more stable in the present invention, as defined in the technical field of the invention: the record carrier 'its special', all of the modulation elements The distance between them is; 々 In addition, as recorded in the technical field of the invention, the recording and/or playback device, Α 'the special city for the modulation component is included for decision by. Or the only distance between the subsequent pheromones to detect the components of the Ρ Ρ 。. This January is based on the following cognition. In the DVD + rWj 'Jin format' is by Yu Wei Xi " Tian 1 In the DVD+RW, the modulation mark is the inverted swing (PSK modulation)' in the new one. In the DVD+RW, the modulation mark is the inverted swing (PSK modulation). In the format, the modulation mark is of the MSK (Minimum Offset Keying) type. It is advantageous to use only one type of modulation mark, because only one type of modulation mark needs to be detected, and this is simple. Barrenness is stored in a combination of multiple markers. Used to indicate bit synchronization, block synchronization, data 丨 and data 0. From the detection of a single tag, it is impossible to retrieve information that also has information on other tags, because it is not known whether the tag is indicating bit synchronization, Block Synchronization, Data 1 or Part of Data 。. The solution of the present invention is to make the distance between each pair of contiguous modulation symbols 疋-' such that the distance between two subsequent modulation symbols Therefore, the solution of the present invention makes it possible to have a very simple self-timed test. The distance between the early modulation mark and the adjacent mark is detected. k select a unique distance, as well as the bit synchronization element, the data bit is turned on - the 兀 素 and the sub-synchronization elements use a single modulation element to obtain reliable detection, the top state and the smallest period of interference. In the scope of the further patent application, a preferred embodiment of the method, the method and the record carrier according to the present invention is provided. [Embodiment] Figure la shows a dish-shaped record carrier, __, , "Eight has a track for recording 9. The center hole 1 0. The track 9 is rotated according to the spiral from the line segment of the record carrier i "upper cross section = recording layer 6 and - protective layer 7. ...in the figure 'where the transparent substrate 5 has a faulty device (such as a known writable or recordable CD), the recording layer 6 can be _β, especially writeable 'examples ,! Composed by phase change, or nine. Through the manufacturing process, the recording layer can also have information 'which first makes the master disc and then multiplies by tableting. The information is organized in an information block format and is optically readable in the form of a continuous area of reflective and less light shots, representing, for example, consecutive pits of different lengths in the CD. In the embodiment, the suffix on the rewritable record carrier is indicated by the feed pattern, which is provided during manufacture of the blank record carrier. The feed pattern is formed by the pre-rails 4, and the pre-rails 4 can travel along the rails 9 during the writing of the heads. The pre-rail 4 can be formed as a deeper or raised portion or as a material property that deviates from its environment. Alternatively, the feeding pattern may be changed by a raised or deep spiral rotation called a convex and concave rail pattern =: into a 'each spiral rotation occurs from a convex (four) concave (and vice versa) to turn I Figure 1 c with Figure 1 d shows two examples of the periodic changes in the physical parameters of the track (called the wobble). Figure 1C shows the change in lateral position, the change in @HUM width. This swing is in the search for _===. For example, the position information such as the oscillating frequency modulation 1 == code or spiral rotation information is encoded in the modulation. A description of a rewritable CD system having such location information can be found in U.S. Patent 2, 3, 12.,398. For example, the feeding pattern can dictate the sub-pattern of the gauge of the tracking signal. In addition, the feeding pattern may include a correction of the convex track area beside the pre-rail adjacent to the pre-rail, as in the D-RW, in the special pattern for recording position information, with pre-pits. Ups and downs of the pre-guided. The change in the feeding track contains a relatively large part of the monotonic oscillation, the so-called unmodulated part. In addition, the feeding device has a relatively small portion in which the frequency and/or phase of the swing 80928-960528.doc 1310551 deviates from the predetermined swing frequency, which is called the modulation portion. In this document, any word pattern of a periodic nature, together with the encoding of any additional elements, is referred to as a servo track having physical parameters that vary periodically over a predetermined frequency, or a wobble having a modulated portion. Figure 2 shows the dual phase wobble modulation. The upper waveform shows the wobble modulation of the block sync pattern, and the second waveform and the third waveform display the wobble modulation of the data bit of the address, and all the modulations are called the address in the pre-rail (Add_h pregr〇) 〇ve, ADIP). The predetermined phase pattern is used to refer to *synchronization symbol (ADIP bit synchronization) and synchronization block synchronization of the full address block), and each data bit (ADIP data =,, 〇", and Amp data =,", ,). The ADip bit sync is indicated by a single inverted wobble (swing well). The Amp block synchronization is indicated by three reverse wobbles immediately after the ADIIM4 element sync, while the data bits have non-inverted perturbations in this region (swings #1 to 3). The ADIP data area includes a plurality of 4· motion periods assigned to represent a data bit. The ADIP data area is indicated by a wobble period of numbers 4 to 7 (= wobble # 4 to 7) in the figure. The wobble phase in the first bisector of the ADIP data region is opposite to the wobble phase in the second bisector in the ADIP data region. Thus, each bit is represented by a sub-region having a different wobble phase (i.e., referred to as a dual phase). The data bit modulation is as follows: Adip data ="〇 „ is represented by two non-inverted wobbles followed by two inverted wobbles, while the ADIP data 丨” is the opposite. In this embodiment, if the two data bit values have the same error probability 'the modulation of the data bits is completely symmetrical. However, other combinations of wobble and reverse wobble may be used, or other Phase value. In a specific embodiment, the predetermined modulation is used after the indication, the empty "ADIP word 80928-960528.doc -10- 1310551 group synchronization (rather than the data bit). A monotonic wobble may be used after the first data bit or a further data bit may be encoded later. Preferably, most of the wobbles are not modulated (also 2' has a nominal phase), thereby determining a simple locking and stable turn-off of the PLL in the side, in this embodiment - 8 possible The modulation swing is followed by 85 non-modulating (ie, monotonic) swings (swing #8 to call. The like-out frequency must be as low as possible, because during the writing, the write clock is derived from the PLL output. .

In addition, the beginning of the non-modulation, and the termination of the non-modulation can also be used for predicate purposes. The total length of the difference is estimated to be 50% of the effective intensity of 80928-960528.doc -II · 1310551. The tender code can be used to encode the address bits in the pre-rail wobble, but for most wobble cycles, the pre-rail wobble must be unmodulated. In order to reliably control the speed of the disk and/or the write clock of the recording process, a large amount of unmodulated wobble is required. Figure 4 shows a modulation plan with separate block synchronization, which is based on the job swing modulation. As described above with reference to Figure 3, in each unit of the matrix shown, 〇 indicates a non-modulating wobble, 1 indicates the initial portion of the i, 5 wobbles that will reverse the phase, and 2 indicates an inverted wobble. And (4) indicates that the phase is re-inverted to the end portion of the 1,5 wobble of the normal state. In each column of the matrix, S6 consecutive wobbles are indicated (lines 37 are *), and each column begins with a bit sync element in row 〇 '1'2. All fine? The address block consists of 83 columns and is numbered according to its number of ADIP bits. , number 〇, 2,4,6 f 8,13,18, etc. The ADIp bit is an isolated bit sync (4〇, 4 small, her p subgroup contains many block sync elements', all of which are covered by many The two elements that are separated by the swing. These synchronous elements are called separate block synchronization. In the ADIP bit, there is a first separate block sync element called sync〇, and in ADIP bit 3, 5 In the 7th, there are three further separated blocks that synchronize the syncin syncl, 871^2 and "1^3. For the maximum reliability of the detection, the knife ion group synchronization elements have different positions. At the beginning of 8, there are 5 columns synchronized by an isolated bit, followed by a repeating pattern of 4 data bits; the value of the data bit element in the figure is an arbitrary instance. Therefore, there are a total of 13χ4 in the ADIP address block. = 52 data bits. In the new format 'we have the following specific implementation. Each ADIP unit has a length of 5 6 swings.

Note that all distances are greater than 1〇, so no two elements are close together, which is an advantage of reducing PLL distortion. Note that all distances are even ' if one of the elements is offset by 1 swing due to a mismeasure You can test this error (but don't fix it). Note that the 'unique aspect is limited to the adjacent elements'. The distance between non-contiguous elements is not unique. For example, distance 26 also occurs between bit synchronization and the second element of sync0 (because
26 =〗6+】〇)，但是在這種情況中，有另一元素（sync〇之第— 元素）在兩者之間。注意，距離10有點特別，其發生於所有 4個字組同步（sync0,…，sync3)。缺點是從偵測距離1〇, 1 法知道偵測到哪一字組同步。優點是對所有4個字組同步 可以使用一種 貞測。26 = 〗 6+] 〇), but in this case, there is another element (the first element of the sync —) between the two. Note that the distance 10 is a bit special, which occurs in all 4 block syncs (sync0,...,sync3). The disadvantage is that from the detection distance of 1 〇, the 1 method knows which block is detected to be synchronized. The advantage is that you can use one type of guess for all 4 block syncs.
