摘要： Lubricant on a rotating recording medium can attach to a slider, particularly on the pad formed in the proximity of the trailing edge. In the slider of this invention, lubricant is not accumulated in the vicinity of the trailing edge and can be drawn to the trailing edge and dispersed constantly. The head slider includes a center pad formed on an air bearing surface in the vicinity of the center of a trailing edge of the slider. A trailing pad is formed so as to bridge a trailing edge of the center pad and the trailing edge of the slider. The trailing pad is formed lower than a highest surface of the center pad and higher than a lowest surface of the slider.

摘要： A flying head slider includes a write head element and a read head element mounted on the slider body. A first transformable actuator serves to protrude the write head element toward a recording medium. A second transformable actuator serves to protrude the read head element toward the recording medium. The first and second transformable actuators can separately be controlled. The amount of protrusion can thus be individually controlled for the write head element and the read head element. The flying height can individually be set above the surface of the recording medium for the write head element and the read head element. Such an adjustment of the flying height enables the write head element and the read head element to simultaneously get closest to the recording medium.

摘要： A head slider in a magnetic disk drive wherein provisions are made to facilitate the evaporation of lubricant adhering to the slider and thereby substantially reduce the chance of the fly height of the slider becoming unstable due to a lubricant drop. A head element, a heat generating element, and a multilayered heat conducting structure formed from multiple layers stacked along a longitudinal direction of the slider, with at least one layer extending up to portions near both lateral sides of the slider, are embedded into a nonmagnetic insulating layer formed in an air exit end portion of the slider. The heat generated by the heat generating element is efficiently conducted throughout the nonmagnetic insulating layer to heat the entire structure of the nonmagnetic insulating layer. As a result, the lubricant adhering to any portion of the nonmagnetic insulating layer is efficiently heated, causing the lubricant to evaporate or flow.
