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 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： 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.
