Invention Description (10) Figure 3 1 is the scrambling table of the scrambling circuit. Best Mode for Carrying Out the Invention Preferred embodiments of the present invention will be described in detail below with reference to the drawings. First, the format of the optical disc according to the present invention will be described as follows. The optical disc of the present invention is an optical disc of the CAV sampling servo system. At the same time, the present invention is described with reference to the broadcast-only ROM disc and the recordable MO disc. Unless otherwise specified, the following will describe the common content of the two discs. The full rotation of the track of the optical disc according to the present invention is divided into 1 4 0 0 segments (segments 0 to 1 3 9 9) as shown in FIG. 1. These segments are classified into address segment ASEG and data segment DSEG. In each track of the address segment A S E G, the position information along the radius of the disc, that is, the track number, and the position in the tangential direction of the track, that is, the * segment number, are pre-recorded by the dent. When manufacturing an optical disc, dents are formed based on this position information. The address segment A S E G appears every 14 segments, so there are 100 address segments in the track. The area from the given address segment A S E G to the next address segment A S E G is a frame, so there are 100 frames in a track, as shown in FIG. 8. The 13 segment between two adjacent address segments A S E G is the data segment DSEG. There are 1 300 data segments DSEG in one track. Each segment contains an area equivalent to 216 servo clocks', that is, 24 servo clocks and 192 servo clocks constituting the servo area ARe and the data area ARd, respectively. With this address segment A S E G, the data area ARd is composed of the address area AR d «and the laser control area A R db. With reference to circles 2 A to 2 D, the format of the MO disc is explained below.

V. Description of invention (11) In the regional ARS, three dents Pa, Pb and Pc, each 2 servo clocks long, are related to the center to center interval of 5 servo clocks. Record, as shown in Figure 2 A to 2 E. There is also provided a focus sampling area AR fs having a length equivalent to 6 clocks in the servo area ARS. By setting the dents P a, Pb and P c of the servo area ARS to have two servo clock lengths, the part without dents, that is, the mirror part, can be reduced, so that it can be used in the dish molding , It is difficult to produce ghost bits. Since RF signals can be stably generated from the dents Pa, Pb and Pc during access, various servo signals, such as tracking servo signals, can be stably generated according to the RF signals generated by the dents Pa, Pb and Pc. In addition, by separating the central distance between the dents Pa, Pb, and Pc by more than a predetermined distance, the RF generated by the dents Pa, Pb, and Pc Data interference between signals can be significantly reduced. In order to reduce the data interference between the dents, what is needed is to separate the dents Pa, Pb, and Pc by not less than 5 servo clocks. The second dent Pb between the 1st and 12th clocks and the third dent Pc between the 16th and 17th clocks are rocking dents, which deviate from the center of the track by ± 1 / 4 tracks, and the tracking error information is provided by the difference in the amplitude of the RF signal generated by the dents Pb and P c. Furthermore, as described later with reference to FIG. 29, the difference in amplitude value on the shoulder portion of the RF signal generated by the pits P b and P c provides the phase information of the servo clock, and the sum of the phase information provides The clock phase information has nothing to do with the tracking status. The paper scale is applicable to the Chinese National Standard (CNS > A4 specification (210 X 297 g *) ^; ΛΙ binding (please read the precautions on the back before filling out this page) -14-A7 3GS463 _____B7_ V. Description of invention (12) (Please read the precautions on the back before filling in this page) The first dent pa on the head end of the servo area A Rs is classified according to its position into the indication segment as the address segment. The address of ASEG is labeled ADM, and the indication segment is a fan. The first sector of the head segment of the zone is marked with STM1, indicating that the next segment is the second sector on the head end of the sector, marked with STM2, and the segment marked with S GM does not belong to any of the above sector marks. "The first dent Pa It becomes the address mark ADM, the first sector mark STM1 and the second sector mark STM2, if they are located in the third and fourth clock periods respectively, as shown in FIG. 2C, during the fourth and fifth clock periods, as As shown in FIG. 2D, and during the fifth and sixth clocks, as shown in FIG. 2E. The starting position of each sector will then be explained with reference to circle 13: the information indicated by the first dent Pa By detecting the maximum value of the difference to check the position of the maximum amplitude value of the generated RF signal , That is, by the so-called differential detection method, such as shown in Figure 3. Since the first dent Pa on the head end of the servo area ARS provides a specific address indication ADM, the first sector is marked STM1 It is marked with the information of STM2 and the second sector, so it is not necessary to record the sector number or track address on the basis of the sector.

The dents record position information in advance, as shown in Figure 4. The 16-bit track address of the access code AC C is divided into groups of 4 bits, and the root t-scale scale is applicable to the Chinese National Standard Falcon (CNS) Λ4 present grid (2I0X 297 mm) '~ -15 -A7 ___B7__, Employee's Consumer Cooperative of the Central Bureau of Economic Development of the Ministry of Economic Affairs A5 ___B7__ 5. Description of the invention (13) According to the Gray code table shown in circle 4, the table is converted to AM = 15 to 12 digits (MSN), A2 = 11 to 8 bits (2SM)-A3 = a sequence of 7 to 4 bits (3SM) and AL = 3 to 0 bits (LSN). If and only if the lowest bit of the 4 bits is [’], the next 4 digits will be the one-time complement. Therefore, the access code is only changed by the pattern between adjacent tracks. Access codes are divided into groups [15, 11, 7, 3], [14, 10, 6'2], [13, 9, 5, 1] and [12, 8'4 by access code bit positions , 0] 'And record a matching class, when in the group [15,11,7,3]' [14 '10, 6, 2] [13, 9, 5, 1] and [12, 8, 4, 0 When the bit number in bit [,] is even, the configuration becomes 1. Therefore, only when the lowest bit of the first 4 bits is [']' By using a complement of 4 bits each time, these access codes can be changed by only one pattern between adjacent tracks, the center The bits of the boring area are formed at one time [〇], in which the pits of the Gray code indicating the two dents below and the pits of the Gray code indicating the two dents above are at the shortest distance, and form [F], one of the dents At the shortest distance, and another dent at the longest distance. Therefore, the central-clock area does not form a continuous mirror area in the radial direction, and therefore, the resin can flow evenly when the disc is molded, and it is possible to obtain a high-quality molded disc. Figure 5 is a part of the access code A C C. Regarding the frame code FRC, the information in the tangent direction of the address segment ASEG, that is, the 8-bit frame address of the specific frame number, is divided into the upper 4 bits and the lower 4 bits, that is, the upper 4 bits FM = 7 Up to 4 bits (MSN) and the lower 4 bits LM = 3 to 0 bits (MSN), and the Chinese National Standard (CNS) A4 specifications (210X 297mm)-I Ί -n J | II order (please read the precautions on the back before filling in this page) 16-A7 _____B7_ 5. Description of the invention (14) The code is recorded in the same way as the Gray code. Although the 8-bit information can be recorded as a frame code, only the number of the address segment ASEG is 0 to 99. At the same time, the focus sampling area AR fs of the servo area ARe is a mirror part and uses a disc drive device for focusing servo, reading power AP C (Automatic Energy Control) or RF signal clamp. The positions of various sampling pulses in these operations are difficult to identify correctly, and therefore, a variation of the servo clock pitch of not more than ± 5 can be expected. Therefore, even if the area with 6 clocks of these changing mirror parts is regarded as a space for sampling with a correct value, it will not be affected by the level modulation of the RF signal level. Printed by the Employee Consumer Cooperative of the Central Standard Falcon Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling in this page) On the other hand, the data area ARd of the DSEG section of the grain section is from 1 7 6 to 3 6 8 It is composed to record user data, 1 2 data clock write area AR ^ first and 4 data clock write area ARP〇, as shown in Fig. 6. The data clock number changes with the area. The first write area AR ^ provides a jaw area to fix the distance required for preheating, starting from the laser irradiation of the drive device until the disc reaches the set temperature, to record and be in the DC when the disc is an MG disc Used to suppress the changes due to the birefringence of the M0 signal. In order to ensure the interchangeability of the format, the ROM disc also has a first-write area ARpr. The post-write area A R PO is used to ensure the elimination of the insufficient distance to erase recorded data and to avoid the interference of data caused by the edge of the groove Gr provided on the M0 disc. The M0 disc is erased by the giant boy in one direction during loading. The data of the same magnetic property is recorded by a large amount of erasing direction as in the first-write area ART PR. Even if the data is not accurate due to insufficient residual heat of the recording medium, this paper standard is applicable to China National Standards (CNS) Λ4 specification (2 丨 0 ^ 297 mm) -17-A7 B7 printed by the consumer cooperation of the Central Central Bureau of Economic Affairs of the Ministry of Economic Affairs 5. The record of the invention description (15) is written on the AR ^ first, and the record data remains unchanged Change, so a stable signal can be produced. In addition, it can effectively provide a data string stabilized at a fixed value to decode the data after the maintenance ratio decoding by recording the same data of 4 data clocks in the post-write area ARPO. Figure 6 is an example of the M0 disc. In the example of the ROM disc, the groove Gr in Fig. 6 has been eliminated. "Since the clamping is generated when the clamping is performed using the write-first area A Rpr2, it is possible to perform an accurate clamping operation." Note that since the pits are not formed in the data rewriting area in advance, the width of the mirror area is larger than that of the CD-only disc. In the CD-only disc, both the data and the dents are pre-recorded as dents. Therefore, by providing the dent Gr in an area equivalent to the data area ARd, as shown in FIG. 6, the mirror portion can be reduced to eliminate the adverse effect of the disc molding on the servo dent. Since the groove Gr is not used for tracking control, it does not need to be particularly accurate. In this embodiment, the 'groove has a depth of λ / 8, where λ is the laser wavelength'. With this only broadcast ROM disc, a fixed dent pa η with 3 data clock areas is provided at the head of the data area A Rd As shown in Fig. 7, the mirror part can be reduced to eliminate the bad effect of the disc molding on the servo dent. Each data sector consists of 6 6 bytes of reference data, 2 0 4 8 bytes of user data (DO to D2047), 256 bytes of ECC (El '1 to E16' 16), 8 bits Tuple CRC (CRC1 to CRC8) and 40-byte user-defined data (UD) 'are composed of 2418 bytes, as shown in Figures 8 and 9. In addition to the reference materials of 6 6 bytes, the paper standard of 2 3 5 2 bytes is in accordance with the Chinese National Standard (CNS) Zhen Xian grid (210 X 297 mm) (please read the notes on the back before filling this page ) • Binding. Order A7 _____B7 5. The data format of the description of invention (1δ) is shown in circle 9. (Please read the precautions on the back before filling this page) Refer to Figure 10, which shows the waveform of the playback signal of 4 pieces of reference materials, each piece contains 8 7 patterns of 4 bytes and 2 7 of 12 bytes The pattern, and all 2 bytes of 0 to allow the detection information to be set, are collectively recorded as reference data. 8 7 patterns are used to set the three-level level (high Η, medium M, and low L) and partial response (1 '1) of the data detection in the maintenance ratio decoding, and the 27-cycle pattern is used to reproduce Correction of the dent displacement due to direct current caused by, for example, recording energy changes. In the data area ARd of the data segment DSEG, the data except the 66-byte reference data is scrambled. The scrambled material is converted by NRZ I and recorded on the basis of the segment. In addition, the disc is a so-called regional CAV disc, and consists of 7 3 6-track gray code parts, the outer edge of the area, 2 track buffer tracks, 5 track control tracks, 2 track buffer tracks, 5 track tracks Control track, 8 4 8 track user area 〇 '8 6 4 track user area 1, 8 8 0 track user area Central Bureau of Economics Bureau member M consumption cooperation.

Therefore, the recording density of the innermost track of the area will not exceed the preset density. The sector accommodation is assumed to be fixed at 2352 bytes. In this example, the sector starts at a fixed segment. If the number of the segments that make up the sector is up and the next sector starts from the next segment without starting the next sector on the redundant byte, then the sector is up. As shown in the last paragraph of Figure 13. Therefore, the sector must be constructed such that segment 0 of frame code 0 is at the head end of the area. If the matching sector is used for most sectors, the capacity of the matching sector can be fixed by making the number of sectors in each area uniform * For the reason of recording area, the number of sectors in the innermost area and other The number of regions is different. Therefore, the sector ends in the innermost area on the track of segment 1 3 9 9. As mentioned above, the user area of the disc is divided into 16 areas, and the number of data bytes (bytes / segment) and the number of segments per sector.

Since each sector is marked with STM 1 'STM2 before the head-end data segment, the specific sector or segment's head-end capital scale applies the national standard of China (CNS & A4 specifications (210X 297 mm)' -24 -A7 A7 Employee consumption cooperation of the Central Bureau of Standards of the Ministry of Economic Affairs du printed B7. 5. Description of the invention (22) The material sector DSEG, even if one of the sectors is marked with defects, the entire sector is still intact, so the defective sectors can be reduced The proportion of occurrence. With the above-mentioned optical disc, by recording the servo dent having a length equivalent to two clocks in the servo area ARS in relation to the generated servo clock SCK, the mirror portion in the servo area ARe can be reduced. This can reduce ghost dents generated during dish molding. By making the dent distance not less than 5 shortest dent widths, data interference can be suppressed to provide a stable servo signal. On the other hand, due to scrambling records The data is recorded on the disc as NRZ I modulation data, the recording pattern can be randomized, and the possibility of continuously generating fixed patterns can be reduced. Therefore, the disc molding can be stabilized, and the reproduction can be reduced in the maintenance ratio decoding The recording capacity of the device. In addition, for the above-mentioned optical disc, the remaining heating time of the above-mentioned optical disc with the laser beam is provided by providing the first write area ARpr and the second write area A RPO in the 10 data area ARd of the data segment DSEG Fixing is possible, therefore, the data can be recorded positively in the data area A Rd. In the above-mentioned disc, since the servo information and address information are provided by the servo area A Rs and the address segment at the equiangular division position As provided by ASEG, the address information can be read in the playback system by the servo clock generated by the servo information, and there is no recording / reproduction of the data, thereby enabling a high-definition and high-speed search. Since most have uniform fans The data capacity of the number of zones is equal, so there is no need to change the number of matching sectors or the exchange of sectors from zone to zone, thereby simplifying the control software.

In addition, since the starting section in each district is arranged the same in each track Location, and each zone starts with the same number of segments, zone management will be more convenient. In addition, since the GCP area that passes through most tracks provides media information in the Gray code, it is recorded in the address segment ASEG The format of the address information is the same. The decoder used to detect the address information can be used simultaneously as the decoder used to read the media information from the reproduction device. Therefore, when cutting, no special signal generator is needed. In addition, the address information can also be read by the reproducing device when the G C P area is read out. Therefore, the pickup position can be positively managed. With this disc, media information specifying the type or format of the media can be provided to the reproduction device from the G C P area. With this CD, information for reading and retrieving control track information can also be supplied through the G C P area. Since the media information of the same content is provided by the G C P area in one track, the highly reliable media information can be obtained on the reproduction device. Since each segment of each track of the G C P area of the disc set in the radial direction provides the same media information, the media information can be read out without using tracking in the reproduction device. In addition, since the G C P area provided inside and near the outer edge of the disc provides the same media information, any inner edge side access start or outer edge side access start can be selected on the side of the reproduction device.

Description of the invention (25) (Please read the notes on the back before filling in this page) The field 'that is, in the GCP area outside areas 0 to 15 as shown in Figure 2 8 shown. If the focus is available in the recording area, if the disc is, for example, an MO disc, or a disc, there is a risk of inadvertent data erasure. Focus on the area with the data formed by dents by capturing, such as GCP Areas, outside the recording area, are protected from inadvertent data erasure. Use D S P 1 〇 2 discernable disc 2 Ο 1 as a broadcast-only disc or recordable MO disc. Since the media information is recorded in the GCP area in the Gray code and in the same format as the address information, the address information and media information can be read and identified by the same method. In addition, because the media information in the Gray code is recorded in many In the GCP area of the track, even if the beam spot position control is incorrect, the media information can be reliably read. When the spindle motor 2 0 3 reaches a fixed r pm and the pickup 205 moves to, for example, the outer edge, the DSP 102 sets a bias current LDB for the I / O block 10 06 Used for the laser diode 207 via the D / A converter 107, the laser diode 207 is provided in the optical pickup 205 for the laser driver 206, and Send a command to the servo time generator (STG) 10 8 to control the on / off of the laser diode 2 0 7 to emit laser light. The bias current LDB is set to the high level and the low level respectively during recording and reproduction. When the laser light is emitted from the laser diode 207, the laser light enters the light detection provided in the optical pickup 2 0 5.

The clock selector 1 1 5 is controlled by the servo time generator (STG) 1 0 8 to select the servo clock signal SCK in response to the replay RF signal from the servo area, and to select the data clock signal DCK in response to Broadcast signal from the data area. The clock during the servo capture operation is the free running frequency of the servo clock generation (SPPL) circuit 1 1 4. For the time pulse during clamping, it uses the signal obtained by dividing the servo clock signal of the free-running frequency at the preset value.

If this pattern is found, when the next pattern appears, open it, that is, on the servo area of the next frame, and check the possible pattern consistency. If this operation confirms the preset number of times, the phase of the servo clock S CK generated by the SP L L circuit 1 1 4 is regarded as locked with respect to the rotational phase of the disc.

(Phase error data) = [(b2 — bl) + (c2 — cl)] / 2 is used to detect the phase error of the servo data and servo clock SCK, as shown in Figure 2 9 * Therefore, by taking In the servo area, the amplitude difference between the shoulders of the rocking pits P b and P c can obtain the phase information. The phase information from the two wobbled dents is added to the phase information generated by the amplitude change due to the tracking position to absorb the gain change. If the SPLL circuit 1 1 4 is locked, the disc reproduction device can recognize the pickup on a segment basis 2 0 5 scanning position, therefore, the position of the first dent P a can be recognized. The four quotients A, B, C, and D shown in Figure 3 are turned on and can be found at the four positions from A to D * where the maximum amplitude is provided between the RF signal sampling. If the result is at position A, it can be understood that the address purlin is shown as address mark A DM and this segment is the address segment at the head end of the frame. Therefore, the sealed frame counter (not shown) used for frame synchronization can be cleared. Since each frame is composed of 14 segments, the window opens every 14 segments. If the consecutively recognizable address is marked, it is judged that the frame synchronization is locked. During the frame synchronization, the address recording position can be recognized, so the access code ACC and frame code RFC can be used by the address decoder (ADEC) 1 1 6 Decoded. With this ADE C 1 16, the 4-bit pattern encoded with the Gray code is decoded by checking the consistency with the Gray code table shown in FIG. 4.

Description of the invention (30) When the pickup 2 0 5 reaches the target track, the tracking operation is performed. The tracking error signal T H E is obtained by taking the amplitude difference of the R F signal reproduced from the wobbling dent in the servo area. D S Ρ 120 2 returns to the tracking control log. The tracking control data is caused by the digitized filter difference value through the PWM circuit 104 to the pickup driver 105 to form a tracking control servo loop. And the head position of the target sector is detected when tracking is applied. As mentioned above, in the immediately preceding segment and header segment of each sector, there are sector designations STM1 and STM2. The relevant sector indicates STM1 and STM2 opens the window at four positions A, B, C and D shown in FIG. If the maximum amplitude position in the RF signal sampled at the four positions A to D is B, then it is the head end of the specific sector. However, if the maximum amplitude position is C, then it is specifically located directly before the sector. Basically, the segment at the head of the sector is determined by converting the sector address provided by the host computer 300 into an actual sector and finding the segment where the sector is located. According to experience, the possibility that the two sector labels change simultaneously is lower than 10_1Q. Therefore, the possibility of damaged sectors is extremely small.
