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.

According to one embodiment, a head slider includes a slider main body, an element embedded film, a head element, and a plurality of recesses. The head element is embedded in the element embedded film. The recesses are distributed in a predetermined area formed on the trailing end surface of the element embedded film.

A head slider is configured to fly a head above a recording medium with an air flow. The head slider includes a recessed portion in a surface facing the recording medium. The recessed portion is formed in a shape that does not form a region in which a shear stress due to the air flow is concentrated.

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.

A head slider includes a medium opposing surface configured to oppose a recording surface of a magnetic recording medium, a head element provided on the medium opposing surface, and an outlet end surface provided on a downstream side of the head element in a direction in which the magnetic recording medium moves relative to the head element, and extending substantially in a perpendicular direction from the medium opposing surface. The outlet end surface has a surface free energy greater than a surface free energy of the medium opposing surface.

In an inspection for judging acceptance of a recording and reproduction head used in a recording and reproduction device, quality information indicating quality of a data signal of a head unit and flying height information indicating flying height of the head unit are acquired, and acceptance of the head unit is judged by a combination of the quality and the flying height.

A head slider includes a medium opposing surface configured to oppose a recording surface of a magnetic recording medium, a head element provided on the medium opposing surface, and an outlet end surface provided on a downstream side of the head element in a direction in which the magnetic recording medium moves relative to the head element, and extending substantially in a perpendicular direction from the medium opposing surface. The outlet end surface has a surface free energy greater than a surface free energy of the medium opposing surface.

A magnetic head slider includes a magnetic head element for reading or writing data from or into a magnetic recording medium. The magnetic head slider flies over the magnetic recording medium by an air flow generated by rotation of the magnetic recording medium. The magnetic head slider includes a slider substrate including a center pad for supporting the magnetic head element, the center pad having a sliding surface opposing the magnetic recording medium and a side surface at a downstream side of the air flow, the slider substrate including a concave portion having a bottom surface recessed from the sliding surface; and an insulating layer covering the side surface of the slider substrate, the insulating layer having an edge surface adjacent to the bottom surface of the concave portion, the edge surface having substantially the same plane with the bottom surface of the concave portion.

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.
