ABSTRACT:
The invention provides a disc device having a disc with a spiral data recording area, a motor for driving the disc, a head for recording data on the disc, reproducing it therefrom and erasing it thereon, a movable mechanism for radially moving the head on the disc, a positioning servo circuit for controlling and driving the movable mechanism, and a microprocessor for controlling the positioning servo circuit. A counter is included in the positioning servo circuit. The counter counts rotation synchronizing clock signals from the motor and outputs a predetermined reference position signal. In accordance with an output signal from the counter, the movable mechanism is driven at the same velocity as that at which the data recording area of the disc is moved in the movement direction of the movable mechanism.
