スク記憶装置の内蔵回路発停制御装置。[Claims for Utility Model Registration] (1) A built-in processor, an actuator circuit that operates the position of a head for reading and writing information on a disk, and a serial signal processing that processes serial signals for reading and writing information in a predetermined manner. The disk surface includes an information recording area and a shipping zone for the head as an evacuation area when not in use. A device that controls the on/off of built-in circuits of a set disk storage device, which detects the presence or absence of operation commands regarding reading and writing of information given to the disk storage device, and selectively turns on/off each built-in circuit according to the detection result. When the circuit on/off control means detects that the operation command has been interrupted for a predetermined period of time or more, the serial signal processing circuit is stopped and the head position control means is used to evacuate the serial signal processing circuit to the shipping zone. After that, the actuator circuit is stopped, and when an operation command is detected by the circuit start/stop control means, the actuator circuit and serial signal processing circuit are put into operation state, and the head position control means automatically moves the head into the state recording area. 1. A built-in circuit start/stop control device for a disk storage device, characterized in that it is adapted to be reset. (2) A built-in circuit of a disk storage device in the device according to claim 1 of the utility model registration claim, characterized in that the built-in circuit is turned on and off by supplying and stopping power supply to each circuit. Start/stop control device. (3) Utility Model Registration A built-in circuit start/stop control device for a disk storage device in the device according to claim 1, characterized in that a selection signal for the disk storage device is used as an operation command.
