    Abstract: A system and method for organizing data on a removable optical disk. The surface area of the disk is divided into concentric data bands (12, 13, 14), each comprising sufficient disk surface area upon which a large number of concentric data tracks may be written. Concentric servo tracks (16, 17, 18), wider than the data tracks, are used to separate adjacent data bands. Each data band utilizes one data track (62) as an address track upon which data identifying the particular data band is pre-written. One data band (60) is set aside as an index band into which indexing information, identifying what data is written in each band, may be written. A desired data record or file can be quickly accessed by first using the index band to identify the address of the band where the desired data is located, and then by directly and rapidly accessing the identified band.

    Abstract translation: 一种用于在可移动光盘上组织数据的系统和方法。 盘的表面积被分成同心数据带(12,13,14),每个数据带都包括足够的盘表面积,可以写入大量的同心数据轨道。 使用比数据轨道更宽的同心伺服磁道(16,17,18)来分隔相邻的数据带。 每个数据带使用一个数据轨道(62)作为地址轨道,在该地址轨道上预先写入标识特定数据频带的数据。 一个数据频带(60)作为索引频带被放置,可以写入标识在每个频带中写入数据的索引信息。 可以通过首先使用索引带来识别期望数据所在的频带的地址,然后通过直接和快速地访问所识别的频带来快速访问期望的数据记录或文件。
