デイスク駆動モータの制御回路。[Claims for Utility Model Registration] (1) In a floppy disk device equipped with a motor that rotates in response to a drive selection signal and enables access to the floppy disk, the motor off delay time of the motor is past. A motor off-delay time setting section T is provided to set the motor off-delay time based on the motor off-delay time of the motor, and the motor is rotated for a time determined by the motor off-delay time setting section T after the drive selection signal is turned off. Control circuit for the floppy disc drive motor. (2) The motor off delay time setting section T includes a timer H1 that measures the drive selection signal off time, a conversion table N that receives the measured value of the timer H1 and determines the motor off delay time; The floppy disk according to claim (1), characterized in that it is equipped with a motor drive timer H2 that operates during the motor off delay time determined by the conversion table N and outputs a motor drive signal. Drive motor control circuit.
