Abstract
A disk drive is provided which uses a disk having a maximal limit cylinder group formed based on an initially recorded servo data before being assembled in a drive body. A CPU sets an actually usable data recording area on the disk by seeking the head in a radial direction over the disk. Further, the CPU allows the generation of a translation table for obtaining a correspondence between inherent physical cylinder address information of an effective cylinder group contained in the set data recording area and logical cylinder address information set to identify the effective cylinder group and allows the translation table to be stored in a memory. The CPU refers to the translation table when, in response to an access request from a host system, control is made to position a head to a target position, and finds-physical cylinder address information corresponding to the target cylinder.
