    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 suspension mechanism of a recording disk apparatus has a head slider mounted on a portion of a load beam in the vicinity of the free end of the load beam through a gimbal spring. The gimbal spring has a central leg portion and two side leg portions, all of which are formed in parallel. The head slider is adhered to the top surface of the central leg portion which is lifted from the side leg portions. A protrusion formed on the load beam or on the central leg portion serves to transfer loading force generated by the load beam to the head slider by a universal joint connection. The gimbal spring is mounted on the load beam such that the longitudinal direction of the central leg portion is normal to the seek direction of the head slider.

    摘要： A magnetic head slider includes a pair of rails formed on a disk opposing surface opposed to a magnetic disk, each of the rails having a flat air bearing surface for generating a flying force during rotation of the disk, a slit formed between the pair of rails at their air inlet end portions, and a groove defined between the pair of rails which is continuous to the slit and wider than the slit, for expanding the air once compressed to generate a negative pressure. The magnetic head slider further includes an electromagnetic transducer formed on an air outlet end at a position where one of the rails is located. The slider has a trapezoidal shape such that its air inlet end is narrower than its air outlet end.

    摘要： A slider body of a magnetic head slider has a leading end located upstream of an air flow generated between the slider body and a magnetic recording medium, a trailing end located downstream of the air flow, and a floating surface opposed to the magnetic recording medium. At least two rails for generating a floating force are provided on the floating surface of the slider body. A magnetic head for reading/writing data is provided at the trailing end of the slider body. A groove formed between the rails is changed in width from the leading end toward the trailing end, thereby generating an attractive force between the floating surface and the magnetic recording medium. Each of the rails has a tapering portion increased in thickness from the leading end toward the trailing end. The tapering portion terminates at a position where each rail is decreased in width from the leading end toward the trailing end. This magnetic head slider is improved in that its floating characteristics are less influenced by working variations of the tapering portion.

    摘要翻译： 磁头滑块的滑块体具有位于滑动体和磁记录介质之间产生的空气流的上游的前端，位于气流下游的后端和与磁记录介质相对的浮动面。 用于产生浮力的至少两个轨道设置在滑块体的浮动表面上。 用于读/写数据的磁头设置在滑块体的后端。 形成在轨道之间的槽的宽度从前端向后端变化，从而在浮动表面和磁记录介质之间产生吸引力。 每个轨道具有从前端朝向后端的厚度增加的锥形部分。 锥形部分终止于每个轨道的宽度从前端向后端减小的位置。 该磁头滑块的改进在于，其浮动特性较少受锥形部分的工作变化的影响。
