Magnetic recording disk cleaning using controlled actuator motion

摘要

In a magnetic recording disk file employing a transducing slider which is closely spaced from the disk surface and has side rail members extending in the direction of disk motion and tapered portions at the leading edge, the disk may be cleaned of contaminant particles by moving the slider in increments from the outside disk diameter to the inside diameter, so that the particles first encounter the slider/inner side rail and are swept away, rather than first encountering the tapered portions and being wedged into the magnetic coating.
