Therefore, when an optical disc is recorded with a copy prevention signal, when the reproduction signal is recorded * If the copy prevention signal is detected >, the recording device can prevent the reproduction signal from being recorded. However, the reproduction device of a ROM disc such as a CD * has never had a function of preventing or prohibiting reproduction from an illegal copy medium. From the K note, there has always been a disc medium that can be reproduced only once, and can be reproduced by M's usual reproduction device. However, when buying this kind of optical disc media, "when copying a commercially available regular optical disc on this media", because the price will be higher than the direct purchase of regular discs, or because the writing device used for copying is expensive And it is not popular * so it is almost unnecessary to take countermeasures against illegal reproduction. The problem is that in recent years, optical discs have become an item for recording software such as games. Such commercially available optical discs with recorded game software have become more expensive than ordinary commercial CDs for music because of the added value of the software. On the one hand, the price of the first-disc media that can be reproduced by ordinary reproduction devices only once is reduced every year. Also, the original production equipment is gradually becoming easier to obtain. -6-This paper size applies the Chinese National Standard (CNS) A4 (210X297 mm).

In this case, the magnetic recording signals in the directions of the arrows 5 1 a, 5 1 b, 5 1 c, and 5 1 d will be recorded on a specific track for a moment, for example, several ms. The magnetic machine can record large currents, so magnetic materials with a high He of 40,000 e can also be recorded. _ = Therefore, as shown in the eighth figure (a), the K eighth figure (b) of the conventional engineering drawing IDs can be recorded for the same degree of operation time in other projects, so CDs can be produced without changing the engineering process. In the case of using a magnetic machine, the magnetic record of ID No can be implemented without rotating the medium 2.

Except for the information on the physical configuration of the disc in all areas of a disc, the information on Table 5 3 2 cannot be used to check whether it is the same original disc. All the data needed to check the address, angle, trace, signal slot depth, and error robustness requires a large-scale device, and its confirmation takes time. Therefore, it is very difficult for an illegal copying company to find a disc that is the same as the CD of the CD that knows the password. Therefore, it has the effect of making it difficult for the illegal copying company to tamper with the ID No. ..- Eight Here, the specific procedure will be explained by the flowchart of Fig. 148. In step 405, when the start command of program No. N is transmitted, in step 405a, it is difficult to read whether the program key information is recorded in the magnetic track. At this time, a recording current will flow through the magnetic head, and erasing of this data will be performed. If it is a regular disc, He is high, so the key information will not be erased. If it is an illegal disc, the key information will be erased because He is low. Next, in step 405b, it will be checked whether there is any data, that is, the password. If it is NO, in step 40 5c, the user will enter the key input command as shown in FIG. 17Q, and in step 4 0 5 d, when the user inputs, for example, 1 23456 ”, check whether it is correct at step 405 e.

The CD is currently copied in various ways, so it is urgent to prevent a copy method. Software for MY code only, -2 3-This paper size is applicable to China National Standard Vehicle (CNS) Α4 size (210 X 297 mm). Central Government Standards Bureau, Ministry of Economic Affairs. 9 A7 B7 V. Description of the Invention () Cannot prevent illegal copying. In the present invention, a method for preventing copying by using the signal slot arrangement and the secret signal method of CD will be described. As shown in the block diagram of the master recorder device in the first figure, the master recorder device 5 2 9 for making a CLV type optical disc original disk such as a CD has a linear speed control section 2 6 a. If it is a CD, one side can be used. While keeping the linear velocity in the range of 1 · 2 in / s to 1 · 4 m / s, the optical pickup head 6 was used to expose the latent image of the signal slot to the photoreceptor on the disc 2 with a light beam, and recorded it. In the case of CD < by tracking loop 2 4, one turn, with a distance of about 1 · 6 ^ m >

Increase the radius r, so the signal increase is recorded as a spiral. Thus, as shown in the third figure (a), the data is recorded in a spiral shape on the original disk. If it is a CAV disc of Vi d e o d sk, the original disc can be reproduced, and the rotation and rotation control can be fully linked to make the original disc. Therefore, when the third party obtains the original data 5 2 8, the master disc recorder device 5 2 9 can easily make a disc master with the same signal groove pattern as the CAV disc manufactured normally. If it is a CAV, the difference between the signal groove pattern of the legally manufactured original disk and the illegally copied original disk will be within several um. Therefore, with conventional methods, it is impossible to distinguish between a regular-made and an illegally-made disc from the physical configuration of the signal slot pattern. On the one hand, if it is a CLV disc of CD-ROM, a certain linear velocity initially set in the range of Ml'2 ~ 1, 4m / s is recorded on the original disc on the spiral portion. If it is CAV, the number of data recorded in a week is always constant. If it is CL V * By changing the line speed, the number of data in one week will be diamondized. If the line speed is slow, the data configuration of the third figure (a) will be 5 3 0 a. If the line -24 " this paper size is common Chinese National Standard (CNS) A4 specification (2) 0X 297 mm) 111--i _---I 1 I--II:--I-— ^ ϋ. .1 -'--- ϋ I— τ Oral Affairs (Please read the notes on the back before filling this page) Economy Printed by the Ministry of Foreign Affairs of the People's Republic of China Huai Bureau Chengong Consumer Cooperative Co., Ltd. Print $ i 462039 A7 B7 V. Description of the invention () When the speed is fast *, the data configuration of the third picture (b) will be 530b. In this way, the usual master disk recording device of M can distinguish between the regular CD and the illegal copy CD data configuration 5 3 0. KK Master disk recording device for general commercial CDs > The line speed can be set with a high accuracy of 0 · 00 lm / s. Then, when making the original disc at a certain linear speed, K has this high accuracy, even if the original CD of 74 minutes is created at a linear velocity of 12 m / s * at the outermost track, when the error is biased to the PLUS side *, 1 1-., August • 783 week error. That is, it can be made into an original disc with a data configuration of 530b with an angular error of 1 1 ′ 783 cycles X36 0 degrees at the outermost periphery than its ideal original disc. Therefore, as shown in (a) and (b) of the third product, the data configuration 530, that is, the addresses 32 3 a to X of each of A1 to A26, will differ between regular CDs and illegally copied CDs. For example, when the quarter area and the configuration area 53 1 of Z1 to Z4 are defined, the configuration area 531 of the address 323 of A1 to A 26 will be different. Therefore, when a correspondence table between two CD allocation areas 531 and addresses 3 23 is created, that is, a physical allocation table 5 3 2, as shown in the third figure (a) and the third figure (b), in the regular CD The physical configuration table 5 3 2 a and 5 3 2 will be different from those of the illegally copied CD. Therefore, this difference can be used to distinguish between regular CD and illegal copy CD. However, it is only possible to create a CD that is difficult to physically copy. Because the method of tampering with the regular CD is a regular CD is very easy, its effect is very weak. As shown in the fifth figure, in the present invention, the physical position table 5 3 2 is created during the production of the CD original disk or after the original disk is finished. This physical configuration table 5 This paper size is applicable to China National Standard (CNS) A4 specifications (2 10 X 297 cm) --------- 二 衣 ------ 1T ----- --0 (Please read the notes on the back before filling in this page.)

And a unidirectional function such as ciphering, and ciphering it by ciphering means 5 3 7 and recording it in the light R OM portion 65 of the CD medium 2 or the magnetic recording track 67 of the CD medium 2 a. Second, in On the drive (dr i ver) side, the code signal 538b is reproduced from the CD medium 2 or 2a, and the code interpretation program reproduced from the optical recording part of the CD is reproduced 5 3 4 | Fuyuan physical configuration table 5 3 2. Reuse The disc inspection program 5 3 a a reproduced from the CD is also obtained from the rotation pulse signal or index generated by the aforementioned FG | Obtain the disc rotation angle information 335 of the current CD address 38a, and compare it with The physical configuration table 532 is compared with the asset section. If it is 〇1 ^ then 5 Ding Hui RT · If it is NO, it is judged to be an illegally copied CD, and the game software is stopped Reproduction of music or music software. The illegally copied CD shown in the third picture (b), its physical configuration table 532b is different from the regular one, so it is withdrawn. As long as the code encoding program 5 3 7 cannot be resolved, it cannot be copied. The CD ca n’t be moved. Therefore, g 卩 causes the copy signal to be copied and also withdrawn. In this way, it has the great effect of completely preventing the reproduction of the illegal copy of the CD. The countermeasures of the CD drive can be found in the following three ways: 1. Make an original disc with the same signal and groove pattern as the CLV disc. 2. Interpret the secret key of the fifth picture by the code decoding program 534 Code encoding program. 3 ^ Analyze all programs in CD — ROM, and modify the code decoding program 534 or disc inspection program 533a * and replace them. Among the above three methods, the third method * is to interpret and modify the program Be-2 6-This paper size applies Chinese National Standard (CNS) A4 specification (210X297 mm) I --- n I ---- I ^ _-n ---- τ η ______ 丨 * 0 ^. { (Please read the notes on the back before filling in this card) 4 62039 A7 B7 V. Description of the invention () It takes a considerable amount of time, that is, a high cost, and the profit of copying CD is relatively small and meaningless. Also, in the present invention, the password decoding program 534 and the disc check program 5 3 3 a are not on the driver side, but are on the media side, so they can be compressed according to the title of CD-R OM and compression. Therefore, due to the interpretation of each title investment program and the interpretation of the secret code, the forecast of the illegal copying business is deteriorated, and the economical effect of preventing copying can be achieved. Secondly, in relation to the second method, in the present invention, the 箪 direction function of the public secret key method such as the R S A method shown in the fifth figure-... For example, you can use the formula C = E (M) = M ° mon η. Therefore, that is, the work cooperation between the Central Standards Bureau of the Ministry of Economic Affairs and Du Yin ^ (Please read the precautions on the back before filling out this page) Make the CD-ROM publicly reveal the code decoding program, which is part of the key, and the other The decryption of the secret code encoding program 5 3 7 of the share key takes, for example, one billion years, so it will not be solved. However, the actual information of the code encoding program 537 may be leaked. However, by the method of the fifth figure, the code decoding program 5 3 4 is located on the media side instead of the drive side. Therefore, in the event of a leak, when the reward is leaked, the password-protection program 1 of the pair can return to the state of preventing copying again. Finally | the first method of making a CL V original disk with the exact same signal slot pattern, using the current CL V master recorder 楗 device 5 2 9, one of its rotation systems generates a pulse of rotation signal, but because It is very difficult to provide a mechanism that can detect and control the rotation angle with high accuracy. However, by capturing the copied rotation angle information and recorded signal of CD, and synchronizing the rotation pulses during copying, it is possible to make a signal slot pattern that is not completely correct, but has some parts with similar position accuracy. But > In this case, the speed must be the same as the linear speed of the CD being copied. 2 7-This paper size applies the Chinese national standard (CNS) A4 grid (210 X 297 mm) 462039 A7 B7 4 The Ministry of Economic Affairs Central S " H?

When recording, in step 5 84b K-set the same rate, for example, the same rate of 1/20 3, to create five combinations of conditional signal slot groups. In step 5 6 4 c 1 find out the physical configuration of the qualified signal group, etc. | Use the laser light to find it from the original disk through the screen display. At step 5 84 d, create the physical configuration table of the qualified signal slot group. At step 5 8 4 e, the physical configuration table is darkened. At step 5 84 f * If it is an optical recording section, then at step 5 8 4 s records this secret code in the second photosensitive part 572a of the original disc. In step 584h, plastic is injected into the original disk to form a disc. In step 584i, a reflective film is formed. In step 584, the step is completed if there is no magnetic layer. Step 5: Record the password in the magnetic recording section at 84m to complete the production of the optical disc. After the original disk is created, the depth of the signal groove is measured and coded, and the configuration table is recorded. The same rate when the original disk is created can be increased to nearly 100%. Here, the detection method of the signal groove depth in the signal groove depth detection unit 555 will be described.

Therefore, as shown in the tenth t: diagram (c), the poles of the regeneration pulses 5 62c, d, and e become lower, and the reference limit level SO at the multi-level quasi-eye tilter 555b is as shown in the tenth t diagram (f ) Although it is possible to output >, at the detection limit level S 1, there is no output as shown in the seventeenth figure (d). Therefore, by taking the logical product of the opposite value of S 1 and S 0, as shown in the seventeenth figure (s), the copy prevention signals 563c, 563d, and 563e can be obtained only in the case of a regular disc. On an illegal disc, the output of the detection limit level g1 is set to 1 and therefore the copy prevention signal is not output. Therefore, the copied disc can be detected. In this case, as shown in the tenth figure (e), the amplitude of the envelope of the light output waveform or the reduction of the modulation rate is detected by the amplitude detection unit 5 5 5. Even if S is obtained, The opposite sign of 1 can also get the same effect. It can be clearly understood from the comparison table of the copy-prevention effect of the twenty-third figure that the original CD or MD original disk making device > has no angular control function, and its disc inspection in the angular direction > is also extremely A Is valid. On the one hand, the original disks used for laser discs (LD), MD, or CD ROMs are made of devices. Because they do not have the control method of chattering, that is, the tracking direction, the displacement in the tracking direction, that is, B, is Is effective. On the one hand, the depth direction, that is, C, if it is added to the conventional circuit, there must be an amplitude or modulation detection circuit in the input circuit. The existing C D I C system cannot detect it. Therefore, at present, A + B · is not only highly effective in preventing copying, but also has interchangeability with the existing IC. Therefore, it is the most effective combination for CD and MD.

The combination of the two parameters of direction and tracking direction is the most effective one. The original disk device of the pair of discs whose modulation is applied in the angular direction and the tracking direction and the depth of the signal groove is shown in FIG. 24 = master disk recorder device 5 2 9 in FIG. 24, which is basically It has almost the same structure and operation as the master recorder device of the first picture already explained, so its explanation and explanation are omitted, and only the differences are described. First, explain the tracking modulation method. The system control unit includes a tracking modulation signal generating unit 564, which sends a control signal to the tracking control unit 24, and performs a tracking with a certain radius r 0 according to the reference track interval 24a. Within the range of the tracking radius r 0 = d r, the modulation process of 陁 K is automatically adjusted. Therefore, on the original disk 572, the trajectory shown in the twentieth figure (a) (b) will be created. This tracking displacement will be sent to the location information input unit 32g of the tracking displacement information unit 32b. In the copy signal generation preventing section 565, a table shown in the thirteenth figure is created with the reference physical arrangement table of the address An, the angle Z η, the tracking displacement τ η, and the signal slot depth Dn 5 3 2 * The password is converted into a password with a password encoder 5 3 7. This code is recorded on the second original disc 5 7 2a on the outer periphery of the original disc shown in Figures 32 and 33, or on the outer periphery shown in Figures 34 and 35. On the original disc of the second field of the Ministry. Also, the modulation D η in the depth direction of the signal slot can be added independently. The system control section 1 of the twenty-fourth figure has a light output modulation signal generating section 566, and the amplitude of the laser output of the optical recording section 3 7 b and the modulation section 5 6 7 is to be reduced to the third As shown in Figure 10 (b), or as shown in Figure 30 (a) | In a certain amplitude, the pulse amplitude is -4 3-(Please read the intent on the back before filling in this page)

Description of invention \) or pulse interval · borrowing Modulated by the pulse amplitude modulation section 5 6 8 | g 卩 can change the actual value of the laser output. After that, as shown in FIG. 30 (: c), photosensitive portions 5 7 3 of the original disk 572 are formed with photosensitive portions 5 7 4 having different depths. Through the Huanghuang etching project, signal grooves 560a to 560e of different depths will be formed as shown in Figure 30 (b), and gp will form deep signal buildings 560a, 560c, and 56 ° d to a depth of about 4,000. * And for example shallow signal grooves 5 6 0 b, 5 6 e with only a depth of about / 6 people. By performing metal plating such as nickel plating on the ifcT original disc 5 7 2, the metal original disc 5 7 5 shown in the 30th circle (e) can be produced, and the molded disc 57S can be formed by plastic molding. In this way, when the amplitude of the laser output is changed into a signal slot on the original disk, as shown in the waveform of the waveform (5) in Figure 31, the extreme value of the reproduction output will be reduced, so the amplitude is limited. The device restricts the specific limit level on time. For signal slots deeper than its signal slot, the pulse amplitude will be detected narrowly, and normal digital output cannot be obtained. Therefore, for the synchronized T original signal shown in the waveform (1) of the thirty-first figure, the pulse width adjustment section 5 6 9 is used to make the width of T + ΔT shown in the waveform (2) occur. For amplitude pulses, as shown by the waveform (S), the digital signal will be corrected. If there is no correction, as shown in the waveform (7), the digital output with the amplitude narrower than the original signal will be obtained, and the digital signal with the wrong result will be output. In this way, the signal slot depth modulation and signal slot depth information D η are sent from the optical output modulation generating portion 5 6 6 to the signal increasing depth responsible portion 3 2 h to prevent copying of the signal by the light-emitting modulation section 5 6 7.

Description of the invention () Actually, the signal m group 5 6 0 If the total signal noise and pulse amplitude types of a group increase, the number of combinations also increases, which can reduce the same rate by several hundred percent. The physical configuration table 5 3 2 is as described above. Because the direction function of the MEMS signal is encrypted, it cannot be tampered unless the secret key is known. Therefore, it cannot be copied unless the copying company makes hundreds of original discs each worth more than 100,000 yuan. That is, although it takes tens of millions to get a swollen copy of the original disk | it does not meet the economic requirements, so the copying business will eliminate the idea of copying and have the effect of preventing duplicates. On the one hand, there are hundreds of types of 10-bit signal slot groups, and the signal slot group is made into hundreds of sisters, although the capacity is only tens of KB. This situation is for a CD-ROM with a capacity of 640MB. In terms of | its impact is only one ten thousandth, so the present invention has the effect of almost not reducing capacity. In the figure, a ROM disc such as a CD is used as an example. However, the same effect can also be obtained when the physical configuration table is secretly recorded and recorded in the recording layer portion of the RAM using a recording disc of a local ROM. .

Description of the invention () The correct signal can be reproduced without error. Generally, a copying business takes a logical signal such as CD-ROM " 101 ', etc., and records the logical signal on an original disc | to make an original disc, and mass-produce duplicate discs. K This logic signal level will not be copied when making a duplicate disc. Therefore, in the recording fields of the offset CP signals and signals, the original disc is copied without the offset voltage becoming stable. On the one hand, the * CP advance signal 726 data is copied to the illicitly copied 'original disk. Load the duplicated original disc into the reproduction device | And as shown in Figure 76 (ia), when the CP advance signal of reproduction + is 72 6 a • As shown in Figure 76 (ch, the limiter 7 2 8 limit The bat level will rise to the + direction. Because the offset voltage is not recorded in the copied disc | as shown in Figure 76 (b) • Wen will be an eye pattern without offset, and the limiter 7 2 8 The limit level is not at the center, so normal signals will not be output. However, the second embodiment of the present invention is based on the CP signal configuration information 7 2 5 or CP advance signal 72 6 * The limit level is forced The ground is set in the + direction. Therefore, the erroneous digital signal is output from the automatic correction limit circuit 7 3 1 of the sixty-ninth figure, and it is determined that it is a duplicated disc in the regular disc comparison section. 7 3 Shift the signal with the eye pattern center shifted from the amplitude center to the CP signal recording field 1. By equalizing the recording amount, the pulse amplitude, that is, the power ratio, can be produced in advance. As shown by the waveform (1) in the t-th figure, when the power ratio control signal is turned into a period TO, if the negative level is negative The picture shows.

Description of the invention () Information 7 2 5 will not be tampered with. Therefore, the duplication company cannot make duplication discs that have the appropriate CP signal on the disc | and make it consistent with the CP signal comparison result. Also, it is impossible to tamper with the CP signal configuration information. Therefore, duplication can be prevented. < Effect of the invention > The optical disc and the reproduction device of the present invention are attached to the optical disc. After the signal of a certain pattern is rubbed, a recording field can be set to record a signal that shifts the center of the eye pattern from the center of the amplitude. After detecting a certain pattern signal on the reproduction device, by intentionally applying an offset voltage to the base value when the RF signal is restored to a digital signal, a signal that shifts the center of the eye pattern from the center of the amplitude is reproduced And assign it to a person who can stop its reproduction if the offset signal is not reproduced. Also, by a reproduction device, the signal is reproduced from a recording area in which a signal that shifts the center of the eye pattern from the center of the amplitude is recorded. The above signals that are restored as digital signals are normal signals. If the restored signals are recorded on a recordable optical disc medium, when they are reproduced * the center of the eye pattern is recorded almost at the center of the amplitude on. Therefore, if the reproduction device shifts the limiting level when the RF signal is restored to a digital signal, it cannot be regarded as a normal signal reproduction when it is reproduced. Its reproduction will stop. Therefore, it is impossible to reproduce the disc.
