200822090 磁軌中心）擺動。磁軌間距是0.74 μιυ。由AD IP單元和載 波決定磁軌的擺動形狀。AD IP單元包含各種資訊項目。 載波被用於產生參考時脈信號。根據此實施例，由一 ADIP單元和後面的載波部分所形成之基本單元被稱作”資 訊框”。如當作例子的圖4所示，假設載波的一週期的尺 寸（又稱作擺動週期）是一擺動，則單一資訊框100具有 93擺動的尺寸（擺動數0到92)。其中，擺動數〇到7 形成AD IP單元101，及擺動數8到92形成載波部分102 〇 另外，AD IP單元101係由擺動數0到3的區域（爲 了方便說明，下文稱作”同步化資訊部分1 〇 1 a”）和擺動數 4到7的區域（爲了方便說明，下文稱作” AD IP資訊部分 l〇lb”）。將各個上述資訊部分101a及101b經過諸如 PSK (移相鍵控）等相位調變。 在AD IP資訊部分l〇lb中，四擺動表示一位元資料。 若位元資料是”〇”，則如圖5 A所示，前兩擺動與載波部分 102同相，而後兩擺動與載波部分102的相位相反。同時 ，若位元資料是”1”，則如圖5B所示，前兩擺動與載波部 分1 02的相位相反，而後兩擺動與載波部分1 02同相。 同步化資訊部分l〇la具有字元同步化（word sync) 信號，也就是說，若下一資訊框100中的ADIP資訊部分 l〇lb是資料的第一位元，則如圖6A所示，具有與載波部 分1 0 2的相位相反之所有四擺動。 如圖7所示，利用52資訊框100獲得一 ADIP字元。 -12- 200822090 引入區中的ad IP單元101包含實體格式資訊。此時體格 式資訊不同於只在位元組16的DVD + R標準（ECMA-349 )或DVD + RW標準（ECMA-3 3 7 )中之實體格式資訊。也 就是說，如圖8所示，將十六進位數字”〇1 h”包含當作位 元組16中的”內容限制資訊”。此”01 h”意指只有以CSS加 密的內容（CSS加密的內容）可記錄在光碟15的資料區 。根據DVD + R標準或DVD + RW標準（爲了方便說明，下 面又統稱作”DVD + R/RW標準”），未使用實體格式資訊的 位元組16，將”00h”設定在其中。 資料區中的AD IP單元101包含位址資訊。此處.，將 位址設定成從碟中心到碟周圍的方向逐漸變小。根據 DVD + R/RW標準，將位址設定成從碟中心到碟周圍的方向 逐漸變大。 如上述，此實施例的光碟1 5是用於記錄的光碟，除 了實體格式資訊的位元組1 6和資料區中之AD IP單元1 〇 1 的位址資訊之外，光碟15都遵守DVD + R/RW標準。 如上述，根據此實施例的光碟1 5，將”內容限制資訊” · (判斷資訊）包含在判斷引入區中的磁軌之擺動形狀的實 體格式資訊中。因此，能夠記錄C S S加密的內容及其密鏡 資訊。結果，能夠以可再生方式記錄C S S加密的:內容。將 CSS加密的內容記錄在資料區，及將其密鑰資訊記錄在引 入區的未使用區。 另外，根據此實施例的光碟15，資料區中之_ ADIP單 元1 〇 1的位址資訊被設定成位址從碟中心到碟周個的方向 -13- 200822090 其是’磁軌的擺動可被判斷成包括具有頻率是dvd + r/rw 標準所規定之頻率的1.5倍之（擺動）部分。結果，磁軌 之擺動的至少一部分具有不符合DVD + R/RW標準。 另外’亦可將磁軌的擺動判斷成包括具有小於 DVD + R/RW標準所規定的振幅之振幅的（擺動）部分。尤 其是’磁軌的擺動可被判斷成包括具有振幅是DVD + R/RW 標準所規定之振幅的一半之（擺動）都分。結果，磁軌之 擺動的至少一部分具有不符合DVD.KR/RW標準。 另外，亦可將磁軌的擺動判斷成包括經過不同於 DVD+ R/RW標準所規定的相位調變之相位調變的.（擺動） 部分。結果，磁軌之擺動的至少一部分具有不符合 DVD + R/RW 標準。 另外，可將資料區中之磁軌的擺動判斷成包括不包括 A DIP單兀1 0 1之（擺動）部分，判斷成包括不包括同步 化資訊部分〗〇 1a之（擺動）部分，或判斷成包括不包括 AD IP資訊部分101b之（擺動）部分。結果，磁軌之擺動 的至少一部分具有不符合DVD + R/RW標準。 也就是說，只需要磁軌之擺動的至少一部分具有不符 合DVD + R/RW標準。在此例中，根據磁軌的擺動之部分 如何不符合DVD + R/RW標準以修正步驟S421 (圖11)中 的判斷。結果，可產生與上述實施例相同的效果。 在上述實施例中，說明光學記錄系統是個人電腦之例 子。另一選擇是，光學記錄系統可以是執行與上述記錄 CSS加密的內容之操作一樣的處理之DVD記錄器。 -24 - 200822090 逐漸變小。因此，光碟1 5被判斷作不正常碟，被不支援 光碟1 5的光碟單元拒絕。因此，能夠防止除了 C S S加密 的內容之外的內容記錄在光碟15上。也就是說，光碟15 充作專用於C S S加密的內容記錄之光碟。 另外，在此實施例中，說明將”內容限制資訊”儲存在 實體格式資訊的位元組1 6中之例子。然而，本發明並不 侷限於此，例如可將”內容限制資訊”儲存在實體格式資訊 的位元組17中。根據DVD + R/RW標準，實體格式資訊的 位元組1 7是儲存”碟應用程式碼”之處。因此，在此例中 ，沒有利用習知光碟單元記錄的相容性。 另外，在此實施例中，說明光碟1 5具有單一記錄層 1 5 c的例子。然而，本發明並不侷限於此，光碟1 5可具有 多個記錄層。 圖9爲根據此實施例之充作光碟記錄系統的個人電腦 (PC ) 10之方塊圖。 參考圖9，PC 10包括主控制器92、充作記錄單元（ 記錄器）和播放（再生）單元之光碟單元20、硬碟驅動器 (HDD ) 94、輸入單元95、顯示單元96、驅動介面97、 及網路控制器98。200822090 IX.

If it is judged that the wobble of the track of the optical recording medium does not have a portion that does not conform to one of the DVD + R standard and the DVD + RW standard, the optical record -10- 200822090 medium is ejected. Thus, the computer readable recording medium ' according to the present invention enables the control computer of the optical recorder to execute the recording method of the present invention. As a result, the content encrypted by c S S and its key information can be recorded in the optical recording medium of the present invention. Thus, the content encrypted by the css and the key information thereof can be recorded in the optical recording medium of the present invention in a reproduction manner. [Embodiment] An embodiment of the present invention will be described with reference to the drawings. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a schematic view showing the cross-sectional shape of a disc 15 which is used as an optical recording medium according to an embodiment of the present invention. < Referring to Fig. 1, a groove G serving as a spiral guiding groove is formed in the recording layer 15c of the optical disk 15. Generally, a portion of the optical disk having a convex shape when viewed from the incident direction of the laser light is referred to as a groove (G), and a portion having a concave shape is referred to as land (L). Here, the groove G is a track for recording information, and data is recorded in the groove G. In FIG. 1, reference numerals 15a, 15b, and 15d represent a first substrate, a reflective layer, and a second substrate, respectively. For example, from the center to the surrounding direction shown in Fig. 2, the magnetic track is divided into a plurality of areas including a lead-in area, a data area, and a lead-out area. The lead-in area is a management information area for storing management information. The data area is the area where the user data is stored (data area). The lead-out area is an area that stores information indicating the end position of the data. For convenience of explanation, the magnetic track is illustrated as a straight line in Fig. 2, and the right and left sides of the paper are respectively defined as the outer (outer) side and the center (inner) side of the optical disk 15. In addition, as shown in Fig. 3 as an example, the magnetic track is swung relative to its center (-11 - 200822090 track center). The track pitch is 0.74 μmυ. The swing shape of the track is determined by the AD IP unit and the carrier. The AD IP unit contains various information items. The carrier is used to generate a reference clock signal. According to this embodiment, the basic unit formed by an ADIP unit and the following carrier portion is referred to as a "information frame". As shown in Fig. 4 as an example, assuming that the size of one cycle of the carrier (also referred to as a wobble period) is a wobble, the single information frame 100 has a size of 93 wobbles (swing numbers 0 to 92). Wherein, the wobble number 〇 to 7 forms the AD IP unit 101, and the wobble numbers 8 to 92 form the carrier portion 102. In addition, the AD IP unit 101 is an area of the wobble number 0 to 3 (hereinafter referred to as "synchronization for convenience of explanation" The information part 1 〇 1 a") and the area of the wobble number 4 to 7 (hereinafter referred to as "AD IP information part l 〇 lb" for convenience of explanation). Each of the above-described information sections 101a and 101b is subjected to phase modulation such as PSK (Phase Shift Keying). In the AD IP information portion l lb, four wobbles represent one bit of data. If the bit data is "〇", as shown in Fig. 5A, the first two wobbles are in phase with the carrier portion 102, and the latter two wobbles are opposite in phase to the carrier portion 102. Meanwhile, if the bit data is "1", as shown in Fig. 5B, the first two wobbles are opposite to the phase of the carrier portion 102, and the latter two wobbles are in phase with the carrier portion 102. The synchronization information portion l〇la has a word sync signal, that is, if the ADIP information portion l lb in the next information frame 100 is the first bit of the data, as shown in FIG. 6A. , having all four wobbles opposite to the phase of the carrier portion 102. As shown in Figure 7, an ADIP character is obtained using 52 information frame 100. -12- 200822090 The ad IP unit 101 in the lead-in area contains entity format information. At this time, the physical format information is different from the physical format information only in the DVD + R standard (ECMA-349) or the DVD + RW standard (ECMA-3 3 7) of the byte 16. That is, as shown in Fig. 8, the hexadecimal number "〇1 h" is included as the "content restriction information" in the byte group 16. This "01h" means that only content encrypted with CSS (CSS-encrypted content) can be recorded in the data area of the disc 15. According to the DVD + R standard or the DVD + RW standard (hereinafter referred to as "DVD + R/RW standard" for convenience of explanation), the byte 16 of the physical format information is not used, and "00h" is set therein. The AD IP unit 101 in the data area contains address information. Here, the address is set to be gradually smaller from the center of the disc to the direction around the disc. According to the DVD + R/RW standard, the address is set to gradually increase from the center of the disc to the direction around the disc. As described above, the optical disc 15 of this embodiment is a disc for recording, and the optical disc 15 complies with the DVD except for the bit information of the physical format information and the address information of the AD IP unit 1 〇1 in the data area. + R/RW standard. As described above, according to the optical disc 15 of this embodiment, "content restriction information" (judgement information) is included in the solid format information for judging the wobble shape of the magnetic track in the lead-in area. Therefore, it is possible to record the contents of the C S S encryption and its secret information. As a result, the C S S-encrypted: content can be recorded in a reproducible manner. The CSS-encrypted content is recorded in the data area, and its key information is recorded in the unused area of the lead-in area. In addition, according to the optical disc 15 of this embodiment, the address information of the _ADIP unit 1 〇1 in the data area is set to the address from the center of the disc to the circumference of the disc-13-200822090, which is the 'track swing'. It is judged to include a (swing) portion having a frequency which is 1.5 times the frequency specified by the dvd + r/rw standard. As a result, at least a portion of the swing of the track has a non-compliance with the DVD + R/RW standard. Alternatively, the wobble of the track can be judged to include a (swing) portion having an amplitude smaller than the amplitude specified by the DVD + R/RW standard. In particular, the swing of the track can be judged to include (swing) equalization having an amplitude equal to half the amplitude specified by the DVD + R/RW standard. As a result, at least a portion of the swing of the track has a non-compliance with the DVD.KR/RW standard. Alternatively, the wobble of the track may be judged to include a (swing) portion that undergoes phase modulation different from the phase modulation specified by the DVD+R/RW standard. As a result, at least a portion of the swing of the track does not conform to the DVD + R/RW standard. In addition, the swing of the track in the data area may be determined to include a (swing) portion that does not include the A DIP unit 兀1, and is determined to include a (swing) portion that does not include the synchronization information portion 〇1a, or judge The inclusion includes a (wobble) portion that does not include the AD IP information portion 101b. As a result, at least a portion of the swing of the track does not conform to the DVD + R/RW standard. That is, only at least a portion of the swing of the track is required to have a non-compliant DVD + R/RW standard. In this example, the judgment in step S421 (Fig. 11) is corrected according to how the portion of the track of the track does not conform to the DVD + R/RW standard. As a result, the same effects as the above embodiment can be produced. In the above embodiment, the optical recording system is an example of a personal computer. Alternatively, the optical recording system may be a DVD recorder that performs the same processing as the above-described recording of CSS-encrypted content. -24 - 200822090 Gradually smaller. Therefore, the disc 15 is judged to be an abnormal disc, and is rejected by the disc unit that does not support the disc 15. Therefore, it is possible to prevent contents other than the C S S encrypted content from being recorded on the optical disk 15. That is to say, the optical disc 15 is used as a disc for content recording dedicated to C S S encryption. Further, in this embodiment, an example in which "content restriction information" is stored in the byte group 16 of the entity format information will be described. However, the present invention is not limited thereto, and for example, "content restriction information" may be stored in the byte 17 of the entity format information. According to the DVD + R/RW standard, the byte group 17 of the physical format information is where the "disc application code" is stored. Therefore, in this example, the compatibility recorded by the conventional optical disc unit is not utilized. Further, in this embodiment, an example in which the optical disk 15 has a single recording layer 15c is explained. However, the present invention is not limited thereto, and the optical disk 15 may have a plurality of recording layers.

The arrows in Figure 1 indicate typical information or signal flows, but do not represent all connections in the block. Further, the optical disc unit 20 supports the above-described optical disc 25. The optical pickup unit 23 is for focusing the laser light onto the recording layer 15 5 of the optical disk 15 and receiving the reflected light from the recording layer 15 c.

When the CD 1 is installed (loaded), the physical information to be stored in the RAM 4 1 is read. (c) Next, in step S403, it is judged whether or not the byte 16 of the extracted entity format information is "01h". That is, it is judged whether or not the installed optical disc 15 supports the CSS-encrypted content recording. Here, since the optical disk 15 is installed, the byte 16 of the extracted physical format information is "0 1 h". Therefore, a positive judgment is made (YES in step S403), and the writing operation is advanced to step S405. That is, it is judged whether or not the installed optical disk 15 supports the content recording of the C S S encryption. (d) In step S405, the CSS-encrypted content is allowed to be written in the data area. Thereby, the CSS-encrypted content is started to be written in the data area via the encoder 25, the laser control circuit 24, and the optical pickup unit 23. (e) Next, in step S4 to 7, it is judged whether or not the content encrypted by the CSS is written in the data area by comparing the amount of data to be written by the main controller 92 with the amount of data written. If the content of the CSS encryption is not completed in the data area, a negative judgment is made (Ν 步骤 in step S 4 0 7 ') and after a predetermined period of time elapses, it is judged again whether or not the CSS encrypted content is completed. In the data area. Meanwhile, if the content encrypted by C S . S is completed in the data area, an affirmative determination is made (YES in step S407), and the writing operation is advanced to step S409. (f) In step S409, the key -19-200822090 information of the CSS-encrypted content is allowed to be written in the lead-in area. Thereby, the introduction information including the key information is written in the lead-in area of the optical disk 15 via the encoder 25, the laser control circuit 24, and the optical pickup unit 23. (g) Next, in step S411, the main controller 92 is notified that the writing of the CSS encrypted content and its key information have been normally ended. Then, the write operation ends. (h) If the byte 16 of the entity format information extracted in step S403 is not "0 1 h", then in step S403, a negative determination (NO in step S403) is made, and the write will be made. The operation proceeds to step S421. (i) In step S421, it is judged whether or not the address information of the ADIP unit in the data area is set to be gradually smaller in the direction from the center of the disc to the periphery of the disc. That is to say, it is judged whether the physical address of the data area is gradually smaller from the center of the disc to the direction around the disc. If the physical address of the data area does not gradually decrease from the center of the disc to the direction around the disc, a negative judgment is made (NO in step S421), and the writing operation is advanced to step S423. (j) In step S423, the disc exit mechanism (not shown) is instructed to exit the mounted disc. (k) Next, in step S425, the main controller 92 is notified to replace the mounted optical disc with the optical disc supporting the content recording of the CSS encryption. Then, the write operation ends. (1) Meanwhile, if the physical address of the data area gradually becomes smaller from the center of the disc to the periphery of the disc in step S42 1, an affirmative determination is made (YES in step S421), and the writing operation is advanced. Go to step S427. (m) In step S427, the main controller 92 is informed to write the abnormally knotted -20-200822090 bundle to the C S S encrypted content and its key information. Then, the write operation ends. (II) Upon receiving "normal end" from the optical disk unit 20, the CPU 92a of the main controller 92 instructs the HDD 94 to erase the contents encrypted by the C S S contained in the hard disk 94a and its key information. The CPU 92a of the main controller 92 notifies the user that the contents of the CSS encryption have been normally ended by displaying the result message on the display portion of the display unit 96. Then, the CPU 92a instructs the optical disk unit 20 to eject the optical disk 15 and end the recording of the content recorded by the C S S encryption. (IV) When receiving "disc replacement" from the optical disk unit 20, the CPU 92a of the main controller 92 notifies the user of the ability to record the CSS-encrypted content by displaying the result message on the display portion of the display unit 96. The disc replaces the installed disc. (V) When receiving "abnormal end" from the disc unit 20, the CPU 92a of the main controller 92 notifies the user that the CSS-encrypted content has been recorded by displaying the result message on the display portion of the display unit 96. failure. As is apparent from the above description, in the P C 10 according to this embodiment, the optical disk unit 20 implements an optical recorder, and a program-implemented processor executed by the CPU 92a and the CPU 92a. The processor implemented by the CPU 92a in accordance with the program execution processing may be partially or entirely formed of a hard disk.
