磁気デイスク装置。 In a magnetic disk device, a driver that drives an actuator provided in the magnetic disk device and a control circuit that controls the driver are operated by supplying power from a drive power source and a control power source, respectively, wherein the control circuit has an output terminal that becomes high impedance when the voltage of the control power supply becomes lower than a predetermined value, and there is an output terminal between the output terminal and the driver on the condition that the output of the output terminal is turned on. A magnetic disk device characterized in that a switching circuit is provided for supplying a control signal to a driver to permit driving of an actuator.
