Magnetic disk control apparatus, magnetic disk apparatus, and method of correcting read error

摘要

A magnetic disk control apparatus includes an error determining unit and a correcting unit. When a correctable read error has occurred during read access to a disk drive, the error determining unit specifies an area on the disk drive where an error may occur due to the same cause as that of the correctable read error. The correcting unit corrects the area specified by the error determining unit by rewriting the area.
