Abstract: Several audio/video streams are recorded in an interleaved manner on logical tracks of variable sizes. These audio/video streams are selected on the basis of an allocation table contained in a random access memory, and which describes the state of occupancy of the logical tracks. The logical tracks include elementary storage portions formed of integer numbers of sectors of the disk. A chaining of the various portions is performed during recording using the index numbers of the preceding and succeeding portions, as well as indications of unknown relationships which will be updated subsequently.

Abstract translation: 在可变尺寸的逻辑磁道上以交错的方式记录多个音频/视频流。 这些音频/视频流是基于包含在随机存取存储器中的分配表来选择的，并且描述了逻辑磁道的占用状态。 逻辑磁道包括由磁盘的整数个扇区形成的基本存储部分。 在使用前后部分的索引号码的记录期间执行各部分的链接，以及将随后更新的未知关系的指示。
