Abstract

PURPOSE:To extend the life of a device and to save the power of a system by arranging a timer circuit in the device, detecting a time in a non-access state, and at the time of arriving at a prescribed time, automatically stopping a spindle motor. CONSTITUTION:The timer circuit 10 is arranged in the FDD device 1. When a controller 2 accesses the device 1, a drive select signal 8 is turned on, so that the signal 8 is inputted to a reset terminal R of the circuit 10 and the circuit 10 is turned to a reset state. When the controller 2 does not access the device 1, the signal 8 is not inputted to the terminal R, so that a timer is driven, and after the passage of the fixed time, a drive control signal 12 is turned of through a drive control circuit 11 and the spindle motor 5 is automatically stopped. Consequently, the life of the FDD device 1, a floppy disk, etc., can be extended and the power consumption of the system can be reduced.
