Abstract

PURPOSE:To reduce the useless power consumption by supplying the power to a limiting circuit set at the side of a system equipment only when a magnetic disk is loaded and having the transfer of signals to a magnetic disk device. CONSTITUTION:A system 8 consists of only the circuits that work regardless of a magnetic disk device 1. Then a control output 12 is turned on and off via a power supply control circuit 11 using a transistor for a circuit 9 which is used in the drive mode of a magnetic disk 5. When the disk 5 is inserted to the device 1, a disk detecting circuit 6 detects the insertion of the disk 5. Then the produced disk-in signal 14 is supplied to the circuit 11 via an input/ output interface 3.
