Abstract
A disk device includes: an optical pick-up, operable to reproduce data recorded in a disk; a flaw detector, operable to output a flaw detecting signal when a flaw formed on the disk is detected; and a jump controller, operable to control a track jump of the optical pick-up including a first track jump and a second track jump subsequent to the first track jump. A timing of starting to control the track jump corresponding to a still reproduction mode is determined based on a rotational position of the disk. When the flaw detecting signal is outputted in a time period in which the jump controller controls the first track jump corresponding to the still reproduction mode, the jump controller sets a timing for stating the second track jump to a timing different from a timing for starting the first track jump.
