Abstract:
1. A disk device comprising: optical pick-up means for reproducing data recorded in a disk; pulse generating means for outputting an FG pulse every time a spindle motor for rotating the disk rotates by a prescribed angle; flaw detecting means for outputting a flaw detecting signal when a flaw formed on the disk is detected; and jump control means for controlling a track jump of the optical pick-up means, the jump control means starting control of the track jump in accordance with a timing of outputting the FG pulse at the time of a still reproduction; wherein when the jump control means detects that the flaw detecting signal is outputted during controlling the track jump corresponding to the still reproduction, the jump control means sets a different timing for starting a subsequent track jump from the previous timing of starting the track jump, and when the jump control means detects that the flaw detecting signal is outputted at the time of starting to control the track jump corresponding to the still reproduction, the jump control means sets the timing of starting the track jump to a timing delayed by a prescribed amount therefrom.
