摘要： A disk drive storage system comprises an array of disk drive units (230). The disk drives (160) contained in the units have a diameter of 65mm and rotate at 10,000 RPM which has the effect of reducing latency. In a preferred embodiment data and corresponding parity information are converted into portions and stored on a respective different one of the disk drive units. Data stored on a filed disk drive unit can be regenerated on a replacement disk drive unit. A disk drive unit can be replaced without powering down the system. Four disk drive units can be arranged in a four drive system to match the space geometry of the traditional half-high flexible disk drive used in a personal computer.

摘要： A method and means is described for writing data on a recording medium, such as a disk or tape, containing servo samples in such manner that the number of servo samples is increased with a minimal increase in overhead (non-data) regions. The tracks on the medium are divided into a plurality of maxi sections, each of which contains all fields with servo and associated overhead information and also a data field. At least one micro servo section containing only a portion of said information is located within each data field.
As each micro servo section passes by an associated recording head, writing and reading of data is temporarily interrupted, but resumed when the micro servo section moves beyond the head, in such manner as to require minimal resynchronisation of said data during reading.
Using a phase continuous clock, data is written in both portions of a data field to either side of each micro servo section in one pass of the disk or tape relative to the head. The micro servo sections contain no timing reference address mark and require no data encoder/decoder flush or synchronisation byte to resume reading in the portion of the data field following each micro servo section.摘要翻译： 描述了一种方法和装置，用于以包含伺服样本的记录介质（诸如磁盘或磁带）的方式和装置，使得随着开销（非数据）区域的最小增加使伺服样本的数量增加。 介质上的轨道被分成多个最大区段，每个区段包含具有伺服和相关联的开销信息的所有域，并且还包括数据域。 仅包含所述信息的一部分的至少一个微伺服部位于每个数据字段内。 当每个微型伺服部分通过相关联的记录头时，数据的写入和读取被暂时中断，但是当微型伺服部分移动超过头部时恢复，以便在读取期间要求所述数据的最小重新同步。 使用相位连续时钟，在磁盘或磁带相对于磁头的一次通过中，将数据写入每个微伺服部分的任一侧的数据场的两部分。 微伺服部分不包含定时参考地址标记，并且不需要数据编码器/解码器刷新或同步字节以在每个微伺服部分之后的数据字段部分恢复读取。

摘要： A data recording disk file is provided with a fixed block architecture sector format that eliminates the ID region. The servo region contains sector identification information in the form of a start-of-track indicating mark recorded in a selected sector of each track and a start-of-sector indicating mark recorded in each sector. A full track number identifier is encoded in the position field within the servo region of each sector. A look-up table is built at format time to map bad sectors out of the disk file. The table contains entries for each cluster of contiguous bad sectors, and is searched at runtime to provide conversion of logical sector location identifiers to physical sector location identifiers.

摘要： A method of positioning separate read and write heads in a disk file compensates for misalignment of the heads when reading and writing data on the disk. Two sets of servo information are generated for each track on the disk. These sets are radially displaced with respect to each other by a distance equal to the respective misalignments between the read and write heads at each respective track. One set is generated by the write head. The other set is generated by the write head while the read head is aligned with said one set. Thereafter, to write data on a selected track, the read head is first aligned with said one set of servo information and then data is written on said track with the write head. To read data on a selected track, the read head is aligned to said other set of servo information and then the data is read by said read head.
