Abstract

PURPOSE:To rotate automatically a spindle motor for attachment and detachment of a disc, and to attach and detach the disc quickly, by rotating a DC motor, where the rise speed is made high only when a door mechanism in case of opening and closing a disc attaching and detaching aperture is opened and a motor on signal is outputted from a disc controller. CONSTITUTION:The motor on signal is generated by a retriggerrable one shot circuit 18 as a motor controlling circuit, At the access time, the one shot circuit 18 is triggerred retriggerrably by the trigger signal from a disc controller 12 to generate the motor on signal, and OR between this signal and the output signal of a switch 9 is operated by an OR gate 17 to control turning-on/off of a transistor 15. That is, a DC motor 14 is rotated when the motor on signal or an output signal related to opening of a door mechanism 8 from the switch 9 is obtained in the side of a disc device 13.
