Abstract
A disk device includes a recording medium having a plurality of recording surfaces, where each of the recording surfaces includes a system region for recording system data related to an operation of the disk device, and a controller configured to control recording of the system data in the system region. The controller is further configured to divide the system data to be recorded into a plurality of portions of divided data of the same size. The controller is further configured, after recording of a first portion of divided data in a first system region disposed on a first recording surface, to start recording a second portion of divided data in a second system region disposed on a second recording surface. The recording of the second portion of divided data is started after a switching time, during which switching from the first recording surface to the second recording surface transpires.
