ABSTRACT:
A disk-like recording medium, such as a compact disc, stores information on tracks recorded on the disc surface. A spindle motor rotates the disc and a read unit, which moves in a radial direction in relation to the disc, reads the stored information off of disc. Servo control of the spindle motor and movement of the read unit is controlled by a control circuit, which acts in response to a recording track detection signal. Servo control of the movement of the read unit is further controlled by a mute circuit, which only allows the read unit to be moved when a control signal generated by the control circuit is above a predetermined voltage level. Limiting when the read unit is driven conserves power.
