Abstract
At the start of operation, a floating magnetic head is brought into contact with the surface of a magnetic disk and the magnetic disk is then rotated to float the magnetic head off the magnetic disk surface. At the end of operation, the floating magnetic head is drawn away from the magnetic disk surface of the rotating magnetic disk and, after the lapse of a certain period of time, the magnetic disk is stopped. This prevents the floating magnetic head from sticking to the magnetic disk owing to dew condensation, permits easy miniaturization of the floating space and provides for increased recording density.
