Abstract:

To set a fixed data read/write time and also to improve the reliability of data.

The (n+1) pieces of disk devices are selected out of (m) pieces of disk devices in all to store the error correction data and (n) pieces of sub- blocks obtained by dividing the error correction data (S1). Then an outer circumference track where the error correction data and a prescribed sub-block are prepared, an inner circumference track where other sub-blocks are prepared and a start logical sector are decided for every selected disk device (S2). The error correction data and the size of every sub-block are decided so as to secure a fixed ratio between the number of sectors of a track and the error correction data prepared on the track or the sub-block size (S3).
