ABSTRACT:
In a disk storage apparatus, an micro processing unit (MPU) as an upper unit calculates a positional relationship between a head section and storage disks using disk management data indicating the positional relationship of servo information among the storage disks to complete a servo lock based on the result of calculation. The servo lock can thereby be executed at high rate without waiting for a disk controller as a lower unit to complete a servo lock.
