The identification information can be displayed information, An apparatus and methods for forming, recording, reproducing, and controlling the recording medium. [Previous Technology] Recently, the standardization of high-density optical discs, a rewritable Blu-ray disc (BD-RE), has developed rapidly, and a large amount of high-quality video and audio data can be recorded thereon. Once the BD-RE specification is established, products using this new optical disc can be marketed in the short term. ·· As illustrated in Figure 1, a BD-RE has an inner hole AMJKC clamping area-# ^ ^ (transition area) ^ BCA (burst cutting area) area, and lead-in area (lead-in area), these areas are arranged sequentially in the direction of radiation. A data area and a lead-out area are respectively located at the center of the disc and the outermost annular zone. The lead-in area is divided into a first protected area (Guard l), a pic (Permanent Information & Control data) area, a second protected area (Guard 2), a second information area (lnf0 2), OPC (Optimum Power Calibration) area, etc. The first protected area and the PIC area are pre-recorded areas, and the new data can be rewritten to correspond to the lead-in area, data area, and lead-out area of the rewritable area. General information that must be permanently saved on a disc can be recorded in PIC area 3 200416724, and the PIC area can be encoded in wobbled grooves of one section by using the HFM (High Frequency Modulation) method. The HFM groove is modulated in a radioactive direction with a higher bandwidth signal to produce a data channel, where sufficient capacity and data rate can be used to replicate information. As shown in Figure 2, bi-phase modulation can be used to perform encoding of data into a waveform slot and thus record it. In this modulation method, when the value of a bit is 0, a conversion is expressed at the beginning of the bit unit; and when the value of a bit is 1, at the beginning and middle of the bit unit Expressed as a conversion. As shown in Fig. 2, when the modulated bit is recorded on the disc, it will deviate from the average centerline of the groove. The length of each bit unit should be 36T, and τ corresponds to the length of one channel bit in the rewritable data area. In parallel with the development of BD-RE, a corresponding read-only disc, 'Blu-ray Read Only Disc' (hereinafter referred to as BD-ROM) has also been developed. As shown in Figure 3, a BD ROM disc may include an internal area, a clamp area, a transition area, an information area, and a margin area. The master data of the wish stream (a / V, You, A l μ, ^, A / V) is recorded in a data area in a resource.

Therefore, a flag may be included in the disc information recorded in the PIC area, which may indicate whether the copy protection information is recorded in the PIC area mark (CPI_rec_Flag), which may indicate the presence of the copy protection information, and the record size is one bit. Tuple. As shown in Fig. 5, a byte is configured to record a flag. The flag indicates that copy prevention occurs in an area reserved for disc information. At the same time, the disc information in the PIC area can be copied multiple times. In the multiple disc information repeated in the PIC area, the flag byte can only be recorded in the first disc information. As illustrated in Figure 6, the flag indicating whether to record the copy protection can be recorded in another area, such as the (outburst cut area) arranged in the PIC area, and the copy protection information is recorded in the PIC area. . Rather than recording the data as straight pits, copy protection information and flags indicating its presence can be recorded as waveform pits. To this end, the dimples may be formed in a necessary number of segments (or in a zigzag form). At the same time, it can be encoded and recorded in the area as wave pits, or linear pits, and / or both. On the other hand, it can be recorded selectively or repeatedly outside the PIC area. Recording is performed by the HFM groove wave method, such as BD-RE. Copy protection information includes a primary value that can be used to encrypt upcoming records without including one. Qi Qiji, the nursing record is recorded in the information BCA code and the concave shape of the PIC topography is recorded in the main data on the data area of 9 200416724. FIG. 7 illustrates an embodiment in which bi-phase modulation is used to encode waveform pits so that data can be detected. In Fig. 7, a bi-phase modulation form is used to encode a '0 1 0 Γ value, such as a bi-phase modulated groove, and a waveform form using a wave pit. Note in Figure 7 The waveform pit of the example contains at least 36T (including marks and spaces), and its 6 3 T signals (marks) constitute a single-bit value. In this embodiment, the left-to-right transition of one of the sequences of pits is marked as' Γ, and the sequence of 6 pits is marked as' 0 ', which are provided in opposite directions. As shown in Figure 7, the bi-phase modulation structure here is different from the structure illustrated in Figure 2. That is, in the method of FIG. 2, when a bit value is 0, a conversion is represented at the beginning of the bit unit; when the bit value is 1, the beginning and middle of the bit unit are expressed by Change it. On the other hand, in the method of Fig. 7, when the value of one bit is represented by a transition at the beginning of the lowest position and the middle of the highest position, and when the value of one bit is 1, the conversion is in the opposite direction. . The combination of bits is used to detect information recorded in the form of waveform pits. The waveform pit may be copy protection information, that is, the main data that can be deciphered in the data area of the recording medium as shown in Figs. 4A to 4F. That is, the waveform pit data can be copied or detected only when the bit modulation data is detected or normally copied. Also, the main data can only be decrypted when the bidirectional modulation data normally detected or copied is used to copy the waveform pit data used for copy protection. Data, recorded in HFM, from one of 6 to 0; used only when the master biphase recorded by the secret or recorded or 10 200416724 when the information is recorded in the pit In this case, it is not necessary to repeat the same pits, but different pits (2T-8T) modulated according to the input information may be recorded. However, in this example, the position of a sequence of pits (i.e., stages) is also shifted every about 18 T to encode the data into a waveform form of a wave pit. When the reflected light reflected from the wave pit is recorded in this form, a four-quadrant light receiving element 1 3 to 16 is used to perform a photoelectric conversion. As disclosed in Figure 7, the photoelectrically converted electronic signals (Ea, Eb, Ec, Ed) are amplified with a current for use in traditional push-pull control. More specifically, the left and right signals (Ea + Eb, Ec + Ed) of the track segment are amplified by amplifiers 10, 11 and 11, respectively, and the left and right signals are output by a differential amplifier 12. Differential signal ((Ea + Eb)-(Ec + Ed)). When the differential signal 501 is converted into a binary signal based on its intensity being higher or lower than a reference value, data encoded in the form of a wave pit can be obtained. Because it is impossible to obtain the signal of the waveform form detection from the waveform pit from the outside, even if the data played from a BD-ROM is copied to a recording medium other than the BD-ROM, the copied data cannot be played back. If the data is not recorded in the form of a waveform, but is recorded in the P 1C area according to a specially agreed format between legally authorized manufacturers, the act of copying a BD-ROM by an unauthorized manufacturer may be more Shape difficulties. Fig. 8 is a simplified diagram illustrating an optical disc device capable of playing a recording medium of one optical disc. The device includes an optical read / write 1 1; VDP (Vedio Disc Play) system 12, which can perform signal processing 200416724 and feed control; and a D / A converter to copy the protection information and perform broadcast playback. " ° It can be prepared according to the relevant description of%. Together with Figure 9 • Use ~ System 12 is possible (CPI-rec-Flag), the flag can refer to 'then' and check whether a flag q is 7κ Put or encode in one; 5 of beuR0m is recorded in the PIC area, and the protection information is recorded (S11); No, the flag in the BCA area of the BD-ROM, which is a copy of the disc information (Su) If it is H, it will be recorded in the protection information of one system. It will then decide whether to detect the flag of Fu Youzheng and check the resumption * 1. The value (S 1 3). If the value indicates the copy protection information It has been recorded that the VDP system 12 prepared by the optical u system δ will perform ... "-work" to extract the copy protection information recorded in the sigh area or encoded in the wave pit; thereafter, the copy is used Protection information, it will perform a series of data playback operations to decrypt and play the records in Encrypted data in the data area (S15). When the value of this flag indicates that copy protection information does not appear, or the flag indicates that the occurrence of copy protection information is not detected, the VDP system 12 will skip detecting the absence of PIC area. The copy protection information is an unnecessary operation, and the operation will be directly executed to read the content recorded in the data area. As shown in the exemplary embodiment of FIG. 5, it can indicate whether there is a record copy protection The information flag, in addition to being included and recorded in the disc information, can be recorded in the PIC area together with the copy protection information. Figure 10 is an exemplary embodiment illustrating this arrangement.
