Abstract
PURPOSE: To reduce head load time and reduce access time by letting a magnetic head make access at a munute distance during moving between the tracks of a disc.
CONSTITUTION: When a magnetic disc 1 is loaded on a turntable 3, a track movement instruction is given from the control part. Then, driving mechanism drives a carriage 7 to move a head 4 to above the tracks. Upon ending of the movement, an FF 14 is set and its output causes a transistor 15 to go ON, thereby applying a supply voltage to a magnet 10. As a result, an arm 6 is pulled down and the head 4 makes access onto the disc 1 until the floating pressure of the head produced by the air flow by the disc 1 and the pressure of the magnet 10 balance so that the head 4 and the disc 1 maintain a minute spacing. The head 4 is then moved onto the specified track by the control part and the head 4 is next contacted to the disc 1, whereby writing and reading are accomplished.
