ABSTRACT:
The present invention achieves improved disk response performance by optimizing the placement of the disk sectors associated with the directory and File Allocation Tables (FATs) on the drive. The physical sectors associated with the directory are located approximately on the middle track of the disk and the FAT sectors are relocated adjacent to the track groups the FAT sectors serve. This novel placement of sectors effectively reduces the disk head seek time and effectively reduces the rotational latency compared to the prior art.
