Abstract
The invention relates to a magnetic recording device comprising (a) a disk comprising a substrate, a metallic magnetic layer, a carbon layer and a lubricant layer; (b) a motor associated with a disk operable for rotating the disk; (c) a head supported on an air bearing slider for magnetically reading data to or magnetically writing data from the magnetic layer on the disk, the trailing surface of the slider coated with a multilayered film having low surface energy; and (d) an actuator connected to the slider for moving the head across the disk. The multilayered film on the trailing surface of the slider substantially reduces stiction of the slider.
