摘要： A magnetic head slider has a plurality of rail planes to generate a floating force by using an air flow passing through a region between a group of the rail planes and a magnetic disk rotated at a constant rotating speed, and the slider floats up into the air according to the floating force. Also, the slider has a first pad arranged near an air inflow end of one rail plane and a second pad arranged near an air outflow end of the same or another rail plane, and a height of the first pad and a height of the second pad respectively range from 20 to 50 nm. Therefore, a coefficient of a friction between the pads and the magnetic disk can be reduced, and the wear of the pads can be prevented. Also, the contact of an electro-magnetic transducing device attached to the air outflow end of the rail plane with the magnetic disk can be prevented.

摘要： The head slider mounts a recording/reproducing element and flies over a recording medium with the airflow generated when the recording medium moves. The head slider comprises a slider body having an air inflow end and an air outflow end, a rail projected from the slider body to define an air bearing surface extended to the outflow end, a projection formed on the rail and between the inflow end and the outflow end, and a recess formed at the outflow end of the rail to make narrow the width of the rail. When the recording medium stops, the head slider and the recording medium are in contact at the projection and the air outflow end of the rail. Since the outflow end of the rail is narrow in width, the stiction can be prevented. Moreover, it is unnecessary to form a projection near the outflow end of the rail and thereby the flying height of the recording/reproducing element can be lowered to improve the recording/reproducing sensitivity.

摘要： The present invention is aimed to provide a head suspension having a high resonant frequency, high shock resistance and low rigidity, which greatly contributes to an improvement of a magnetic disk apparatus. In an oscillation-type actuator, at least a part of a spring arm of the head suspension having a data reading/writing head slider 1 is made of an anisotropic layer whose rigidity varies in accordance with a direction. In this case, the anisotropic layer is laminated so that the high rigidity modulus orientation direction is different according to layer.

摘要： A rail is formed on a medium-opposed surface of a slider body in a flying head slider. An air bearing surface is defined on the upper surface of the rail, which faces the medium. Projections are formed on the medium-opposed surface. The projections serve to space the air bearing surface from a medium such as a recording disk when the slider body contacts the recording disk. A trailing end of the rail is narrowed laterally along the trailing end of the medium-opposed surface. Even when the slider body contacts the recording disk at the trailing end, in addition to the projections, the contact area between the slider body and the recording disk is reduced because of the narrowed trailing end. Since the rail is narrowed without changing its original thickness or height from the bottom base of the medium-opposed surface, no additional processing is required to form the air bearing surface.
摘要翻译：轨道形成在飞头滑块中的滑块体的中等相对表面上。空气轴承表面限定在轨道的面向介质的上表面上。投影在中等相对表面上形成。当滑块体接触记录盘时，突起用于将诸如记录盘的介质的空气轴承表面空间。轨道的后端沿着介质相对表面的后端横向变窄。即使当滑块体在后端接触记录盘时，除了突起之外，由于尾端变窄，滑块体和记录盘之间的接触面积减小。由于轨道变窄而不改变其初始厚度或高度与中等相对表面的底部基座，所以不需要额外的加工来形成空气轴承表面。

摘要： An air-bearing head slider supports an electromagnetic transducer opposed to a rotating recording medium or magnetic disk. The slider includes a slider body having a bottom surface opposed to the rotating magnetic disk, the bottom surface having an air-entry end and an air-delivery end with respect to an air flow generated between the slider body and the rotating recording medium. A central rail is provided on the surface of the slider body at the air-entry end. The central rail extends from the air-entry end and terminates on its way to the air-delivery end. Two side rails are provided on the surface of the slider body at the air-delivery side and extend from the air-delivery end and terminate on their way to the air-entry end. An air flow passage, extending from the air-entry end to the air-delivery end, includes air gaps defined between the central rail and the two side rails and an area on the bottom surface located downstream of the gaps, so that a negative pressure is generated in the downstream area due to the air flow passing through the gaps.

摘要： A flying head slider includes a slider body. The upstream or leading end of a bottom surface on the slider body is defined along a first datum line extending in the lateral direction of the slider body. The first datum line may be set perpendicular to the longitudinal centerline of the slider body. The upstream or leading end of the front air bearing surface is defined along a second datum line intersecting the first datum line at a predetermined inclined angle. As the incidence angle of an airflow colliding against a step defined at the leading end of the front air bearing surface gets decreased, the pitch angle of the slider body also gets decreased in the flying head slider during flight.

The head slider includes a front rail formed on the disk opposing surface in the vicinity of the air inlet end, the front rail having an air bearing surface and a step surface lower in level than the air bearing surface; a transducer formed in the vicinity of the air outlet end; and a first groove for expanding air once compressed by the front rail to generate a negative pressure. The head slider further includes a second groove formed on the step surface near the air inlet end except opposite side portions of the step surface. The step surface reaches the air inlet end at the opposite side portions.

摘要： A head slider, usually employed in a recording disk drive, comprises a chamfered vertex defined at a corner of a polygonal bottom surface surrounded by a contour separated from a contour of an air bearing surface. Even when the chamfered vertex collides with the surface of a recording disk, a scratch or damage may be hardly generated on the surface of the recording disk, as compared with a keen vertex. The recording disk drive employing the head slider may enjoy an improved shock resistance.

摘要翻译：飞头滑块包括滑块体。沿着滑块体的横向方向延伸的第一基准线限定滑块体上的底面的上游或前端。第一基准线可以垂直于滑块体的纵向中心线设置。前空气轴承表面的上游或前端沿着与第一基准线以预定倾斜角相交的第二基准线限定。由于与在前空气轴承表面的前端限定的台阶碰撞的气流的入射角减小，所以在飞行中飞头滑块中滑块体的俯仰角也减小。
