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 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 memory disc for use in a memory disc, comprising a lubricant layer which consists essentially of a non-fluid bonding lubricant, or comprises a lubricant layer which contains at least 90% of non-fluid bonding lubricant. Such memory disc is fabricated through steps of: forming a protective carbon layer; coating a lubricant on a disc substrate; subjecting the resultant substrate to an adhesion treatment to form a bonding layer of lubricant adhering to the disc substrate; and removing a free fluid layer of the lubricant remaining on the bonding layer. Thus, the memory disc has essentially no fluid component that can flow during read/write operations.

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.
摘要翻译：磁头滑动器安装记录/再现元件并且在记录介质移动时产生的气流飞过记录介质。磁头滑动器包括具有空气流入端和空气流出端的滑块主体，从滑块体突出的轨道以限定延伸到流出端的空气轴承表面，形成在轨道上并且在流入端和流出端和形成在轨道的流出端处的凹部，以使轨道的宽度变窄。当记录介质停止时，磁头滑块和记录介质在轨道的突出部和空气流出端处接触。由于轨道的流出端的宽度窄，因此能够防止静止。此外，不需要在轨道的流出端附近形成突起，从而可以降低记录/再现元件的飞行高度以提高记录/再现灵敏度。

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.
