  • Patent number: 6134586
    Abstract: A video server with a file storage system for a disk drive in which the disk is logically divided into radial zones and sequential portions of files are stored in different zones according to a predetermined order of zones so as to reduce the average seek time during interleaved access to multiple files. When two files are stored with sequential portions of a first file located sequentially around the inside radius of the R/W surface and sequential clusters of a second file located sequentially around the outside radius of the R/W surface and the clusters of the files are read interleaved (taking turns) then the average seek time for reading the files is approximately equal to the maximum seek time. When the sequential clusters of the files are intentionally dispersed in a pattern in the zones, then the average seek time for reading the files is approximately 1/2 the maximum seek time.
