Abstract
A disk apparatus in which a seek operation of one of a plurality of heads to a target position on one of a plurality of recording disks is performed by using location data on the one of the recording disks, includes a memory unit in which at least defect location data is stored, the defect location data indicating a location of a defect on the recording disks. A defect location determining unit determines a seek path of one of the heads from a present position to the target position prior to performing the seek operation, and detects whether the defect location is included in the seek path. A seek control unit performs the seek operation of the one of the heads by using the location data on the one of the recording disks, and inhibits using the location data at the defect location when the defect location determining unit detects that the defect location is included in the seek path.
