ABSTRACT:
An arrangement for reducing the stiction bond at power-up time between an slider parked on a disk or other magnetic recording medium. A thermally expansive medium such as alumina is included in the slider body thermally adjacent to the write element. At power-up time or when a failure of the disk, etc. to rotate is detected during startup, a current is applied to the write element. The volume expansion resulting from the heat causes a change in the shape and/or location of the slider surface in contact with the disk and thereby breaks or reduces the slider/disk stiction bond.
