Abstract:
A method includes tracking access to files that are stored on a single disk, and identifying a file access sequence involving a first file and a second file stored on the disk, wherein the first file is accessed before the second file. The method further includes determining a time differential between a time that the first file is accessed and a time that the second file is accessed, and determining a direction and speed at which a drive head of the disk can move between sectors and tracks of the disk. Still further, the method includes migrating one or both of the first and second files to a new location on the disk so that, after the drive head of the disk has read the first file, the drive head is repositioned at a beginning of the second file in a period of time that is a function of the time differential.
