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： A first protection layer is overlaid on the surface of a recording layer in a recording medium. A second protection layer is overlaid on the surface of the recording layer at a position adjacent the first protection layer. The second protection layer has a composition different from that of the first protection layer. The first and second protection layers have different compositions, so that the overall protection layer is allowed to have an unequal property. The second protection layer may have a hardness higher than that of the first protection layer. A higher hardness of the second protection layer serves to avoid damages on the surface of the recording medium rather than the first protection layer. The recording medium can reliably be protected from collision or contact of an object.
摘要翻译：第一保护层覆盖在记录介质中的记录层的表面上。在与第一保护层相邻的位置处，在记录层的表面上重叠第二保护层。第二保护层具有不同于第一保护层的组成。第一和第二保护层具有不同的组成，使得整个保护层被允许具有不相等的性质。第二保护层的硬度可以高于第一保护层的硬度。第二保护层的较高硬度用于避免在记录介质的表面而不是第一保护层上的损坏。可以可靠地保护记录介质免受物体的碰撞或接触。

摘要： A protector protuberance is formed on a head slider incorporated in a recording medium drive such as a hard disk drive. The protector protuberance is allowed to collide against a contamination on a recording medium in front of a head element mounted on the head slider. The head element can be protected from collision against the contamination behind the protector protuberance. The protector protuberance is located as close to the head element as possible. Even with a smaller protector protuberance, the front and rear support protrusions contact the recording medium so as to hold the slider body above the surface of the recording medium. An increase can be prevented in the adsorption acting between the slider body and a lubricant agent spreading over the surface of the recording medium. A smaller protector protuberance enables the head element to approach the recording medium as close as possible upon read/write operations.
摘要翻译：保护器突起形成在并入记录介质驱动器（例如硬盘驱动器）中的磁头滑块上。允许保护器突起与安装在头滑块上的头元件前面的记录介质上的污染物碰撞。可以防止头部元件与保护器突起后面的污染物碰撞。保护器突起位置尽可能靠近头部元件。即使具有较小的保护器突起，前后支撑突起接触记录介质，以将滑块体保持在记录介质的表面上方。可以防止在滑块体和在记录介质表面上扩散的润滑剂之间的吸附作用的增加。较小的保护器突起使得头元件能够在读/写操作时尽可能接近记录介质。

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.
