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： A magnetic disk drive has a magnetic disk and a magnetic head assembly mounted on an arm. The assembly is utilized in the recording and reproducing of data on and from a recording/reproducing surface of a magnetic disk. The magnetic head assembly includes a support body for connecting the magnetic head assembly to the arm and a head chip attached to the support body. The head chip is configured and arranged for making substantially continuous sliding contact with the recording/reproducing surface of the magnetic disk during recording/reproducing. The head chip includes a wafer base, a read/write element for recording/reproducing data from the recording/reproducing surface of the magnetic disk. The read/write element is formed from a plurality of thin film layers superposed upon the wafer base and the head is elongated in a direction generally perpendicular to a plane generally defined by the recording/reproducing surface.

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 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.
