ABSTRACT:
A disk recording medium includes a servo track pattern where a gray code field has been deleted, capable of embodying a high capacity hard disk drive. The hard disk drive which uses as a recording medium, a disk having a plurality of servo sectors for each track, includes: a first plurality of servo track patterns on each track, the number of first servo track patterns equal to the total number of first servo sectors existing on each track divided by the number of heads of the hard disk drive, each of the plurality of servo track patterns having a gray code field for providing information for each track; and a second plurality of servo track patterns on each track, the number of second servo track patterns equal to the total number of servo sectors existing on each track minus the number of first servo track patterns, each of the second plurality of servo track patterns corresponding to the first servo track pattern but with the gray code field deleted.
