ABSTRACT:
A hybrid servo pattern, which is printed onto a disk, for use in a disk drive. The hybrid servo pattern is used to position a head relative to the disk. In one embodiment, the hybrid servo pattern includes gray code and chevrons. The gray code provides coarse positioning information, and the chevrons provide fine positioning information.
