摘要： A magnetic head which can fly over a surface of a magnetic recording medium comprises a main body fitted into a supporting arm, rail surfaces formed in the main body to serve pneumatic bearings, and projections formed on the rail surfaces and having surfaces opposing a magnetic recording medium. The projections have larger surface roughness than that of the magnetic recording medium, whereby wear-out rate of the projections provided on the magnetic head can be reduced and also the projections can be firmly brought into contact with the surface of the magnetic recording medium.

摘要： A magnetic head slider comprises a slider body comprising a base portion made of an altic material and an element-forming portion, made of alumina, having formed thereon magnetic conversion elements. Slider-flying rails protruding beyond the surface of the slider body are provided. A first protection film is formed on the surface of the slider body to cover a boundary between the element-forming portion and the base portion to thereby prevent a lubricant of a magnetic disk from depositing on the boundary between the base portion and the element-forming portion. Second protection films are formed on the surfaces of the slider-flying rails to protect the magnetic conversion elements from being corroded and damaged. Further, when pneumatic bearings are provided on the slider-flying rails, third protection films are formed on the surfaces of the pneumatic bearings.

摘要： A medium-opposed surface of a slider body is opposed to a recording medium. A rail is defined on the medium-opposed surface. A groove is defined on the medium-opposed surface between the trailing end of the rail and the trailing end of the medium-opposed surface. A lubricating agent is forced to flow into the groove based on the meniscus effect. Airflow acting on the medium-opposed surface serves to lead the lubricating agent along the groove to the edge of the medium-opposed surface. The lubricating agent is then blown over from the end of the groove at the edge of the medium-opposed surface. The lubricating agent is in this manner prevented from staying between the trailing end of the rail and the trailing end of the medium-opposed surface. The head slider is thus allowed to keep flying in a stable flying attitude.
摘要翻译：滑块体的介质相对表面与记录介质相对。轨道被定义在介质相对表面上。在轨道的后端和介质相对表面的后端之间的介质相对表面上限定凹槽。基于弯月面效应迫使润滑剂流入凹槽。作用在介质相对表面上的气流用于将润滑剂沿着槽引导到介质相对表面的边缘。然后，润滑剂在介质相对表面的边缘处从槽的端部吹出。以这种方式防止润滑剂停留在轨道的后端和介质相对表面的后端之间。因此，头部滑块能够以稳定的飞行姿态保持飞行。

摘要： A head slider is composed of a substrate having a transducer on its outflow end, a rail plane formed on a surface near both sides of the substrate facing a magnetic disk. The head slider further includes a plurality of projection elements formed on the rail plane. When the slider is floating over the magnetic disk, the distance between the projection elements and the magnetic disk is greater than the distance between the outflow end of the slider and the magnetic disk.

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。
