Abstract
A head element is made into contact with the surface of a recording medium so as to realize a float-up degree of 5 nm. Accordingly, a slider incorporating the head element for recording and reproducing data to and from the recording medium is provided thereon with a plurality of pads having step parts, and one of the plurality of pads, on which the head element is mounted, has a height which is less than that of the other pads. Thus, the pads other than the pad on which the head element is mounted are floated up while the pad on which the head element is mounted is stably made into contact with the surface of the recoding medium by means of a meniscus suction force and a damping action of lubricant applied on the surface of the recording medium.
