Abstract

PURPOSE:To reduce power consumption as well as action noises by using a control means for driving a cooling fan continuously only in a disk access action mode and then intermittently in other action modes respectively. CONSTITUTION:A hard disk device is provided with a hard disk, a disk driving part and a magnetic head. The record/reproduction part and a hard disk mechanism part 1 of the hard disk device receive cooling air from a cooling fan 2. A CPU 9 consisting of a microcomputer, etc. performs record/reproduction operation as well as drive control with the disk. A fan control part 3 containing a microcomputer, etc. turns on a switch 6 continuously in an access mode where the hard disk is recorded and reproduced. Thus the fan 2 is driven continuously. While the fan 2 is driven intermittently in other modes.
