装置。 A spindle servo device that drives and controls a spindle motor for rotationally driving a disk-shaped recording medium, which is equipped with two types of equalizer circuits with different characteristics and plays back a disk-shaped recording medium on which information is recorded at a constant linear velocity. The spindle is characterized in that the two types of equalizer circuits are used by switching between a normal playback operation in which recorded information is continuously played back along a recording track and a scan operation in which playback is performed while skipping over a plurality of tracks. Servo device.
