ABSTRACT:
According to one embodiment, a disk drive is disclosed which has an offset measuring function for measuring a dynamic offset value necessary to a dynamic offset control using a DTM (discrete track media) type disk. A CPU (microprocessor) included in the disk drive writes offset measuring position information to an optimum position of lands on the disk and calculates a dynamic offset value based on the offset measuring position information.
