    • Conventionally, multiple session discs are provided with backward going pointers (P). It is now disclosed that it is possible to navigate a multiple session disc without the provision of such pointers (P). A multiple session optical disc which also acts to copy protect audio data has a first audio session (40) and a second data session (60). The data session (60) has a Lead-In (LI), a program area (32), and a Lead-Out (LO). It also has a primary volume descriptor (50) containing control data identifyîng the files within the data session but there is no pointer from the Lead-Out (LO) of the session (60) to any part of the program area (32). The audio session (40) has a program area (32) extending between the Lead-In (LI) and the Lead-Out (LO). To copy protect the audio information, the audio data (40) is hidden from a data reader. For example, the Lead-In (LI) to the audio session (40) and the Lead-In (LI) to the data session (60) may each erroneously identify the data in the audio session as data.
    • 通常,多个会话盘设置有后向指针(P)。 现在公开了可以在不提供这样的指针(P)的情况下导航多个会话盘。 还用于复制保护音频数据的多会话光盘具有第一音频会话(40)和第二数据会话(60)。 数据会话(60)具有引入(LI),程序区(32)和引出(LO)。 它还具有包含控制数据的主卷描述符(50),其中识别数据会话内的文件,但是没有从会话(60)的导出(LO)到程序区域(32)的任何部分的指针。 音频会话(40)具有在引入(LI)和导出(LO)之间延伸的程序区域(32)。 为了复制保护音频信息,音频数据(40)从数据读取器被隐藏。 例如,到音频会话(40)的导入(LI)和数据会话(60)的导入(LI)可能每个将音频会话中的数据错误地标识为数据。
