摘要： A DVD terminal (20) makes a request for sending a sub-content to an authentication server (40) (in this case, attaches the “model name and serial number” of the DVD terminal (20)) (S302). The authentication server (40) generates a random number R (S304) and sends it to the DVD terminal (20) (S306). The DVD terminal (20) reads a terminal key and a terminal ID that are stored in a terminal information memory unit (25), decrypts the received random number R using a terminal key (SK_X) (S308) and sends this and the terminal ID (ID_X) to the authentication server (40) (S310). The authentication server (40) verifies the random number R and the terminal ID that are received from the DVD terminal (20) and encrypted, and judges whether the DVD terminal (20) is the authenticated terminal or not (S312).

摘要： A track skipping detection and control arrangement for an optical recording and reproducing disc formed with guide tracks for use in an optical information recording and reproducing apparatus. According to the track skipping detection and control arrangement of the present invention, any sudden track skipping which may take place during recording can be instantaneously detected by the track traversing signal so as to reduce the recording power for the prevention of erroneous recording to neighboring tracks. Moreover, by distinguishing the track traversing signal detected during the jumping operation for repeated continuous reproduction of the particular one track of the optical disc having spiral tracks, from the traversing signal due to the track skipping, erroneous recording may be similarly prevented also with respect to the optical disc having the tracks in the spiral configuration.

摘要： In an optical disc having a file region and a directory region for carrying various pieces of information or data, one or more designated information can be erased by irradiating a laser light beam on a corresponding region in the file region where the light beam is modulated by a superposing writing signal which may be a d.c. or a predetermined a.c. signal. When it is intended to renew the information, designated information is first read out and stored in an external memory prior to performing superposing writing. Meanwhile, the data is renewed and is then written on an unused region in the file region. The directory of the renewed data region is also written so that the renewed information will be read out by searching the new directory. In another embodiment of the invention, the information in the file region is not erased to renew the same, but its directory is erased by superposing writing. A new directory for a renewed information, which is written in unused region in the same manner as the above, is written so that the renewed information can be read out by using the new directory. When reproducing, an envelope of the reproduced signal is detected to see whether information can be read out or not. Thus, erased information is skipped to reproduce only unerased information.
摘要翻译：在具有用于承载各种信息或数据的文件区域和目录区域的光盘中，可以通过将激光束照射在光束被调制的文件区域中的相应区域上来消除一个或多个指定信息一个叠加的写信号可能是直流电或预定的a.c. 信号。当意图更新信息时，首先将指定的信息读出并存储在外部存储器中，然后再进行叠加写入。同时，更新数据，然后写入文件区域中的未使用区域。更新的数据区域的目录也被写入，以便通过搜索新的目录来读出更新的信息。在本发明的另一个实施例中，文件区域中的信息不被擦除以更新它，但是通过叠加写入来擦除其目录。以与上述相同的方式写入未使用区域的新信息的新目录被写入，以便可以通过使用新目录读出更新的信息。当再现时，检测再现信号的包络线以查看是否可读出信息。因此，擦除的信息被跳过以仅再现未被更新的信息。
