ABSTRACT:
When the driving process of a floppy disk drive is operated, the back light is turned off to conserve energy according to a control process. The back light is also controlled when the disk drive is driven at intervals with short stop periods to light only after a determined interval of time elapses to prevent blinking of the back light while the disk drive is driven.
