ルサーボ装置。A spindle servo device that controls the rotation of a disc set in a disc player to a predetermined number of revolutions, which includes speed detection means and phase detection means that are switched by a mode detection means, and uses a reproduction synchronization signal as a control input to detect pauses, pauses,
When in a mode for jumping tracks on a disk such as scanning or searching, the speed detecting means is switched to control the spindle motor by the output of the speed detecting means, and during normal playback, the phase detecting means detects the difference between the playback synchronization signal and the reference signal. A spindle servo device characterized in that it is configured to determine a phase difference and control a spindle motor based on this phase difference.
