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, and the first projection arranged on the rail planes near an inflow end of the substrate, and the second and third projections formed on the rail plane near an outflow end of the substrate.

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.

A magnetic head has a recording/reproducing element which is embedded in an insulation layer made of an AlO.sub.x thin film and a leading end of which is positioned at a medium opposed face. A high-hardness coating layer or a high-thermal conductivity coating layer made of diamond-like carbon or the like is disposed on a peripheral region of the medium opposed face, excluding the leading end of the recording/reproducing element and a region in the neighborhood thereof. Even in the case where the magnetic head is applied to a magnetic disk apparatus of contact recording/reproducing system, it is possible to greatly restrain wear of the leading end of the recording/reproducing element and the region in the neighborhood thereof. Further, the heat dissipation characteristic of the leading end of the recording/reproducing element can be improved greatly. The dishing of the leading end of the recording/reproducing element can be reduced to a great extent by so etching the peripheral region of the medium opposed face that the leading end of the recording/reproducing element is projected; forming the high-hardness coating layer on an etched region; and processing the projected region by wear in a final process.

A magnetic head slider has a protective film which forms, at a portion of an air bearing surface nearer to the air incoming side from the center, a hill-shaped crown of a desired height sufficient in terms of the mechanical durability of the protective film by a variation of the film thickness of the protective film and which is flat with a film thickness of 10 nm or less on the air outgoing side at which a magnetic head element is provided. This protective film may be a diamond-like carbon film (DLC) or a single layer structure of polycrystalline Si or else a layered structure of a combination of them.
摘要:
A process is described for the modification of the outermost atomic layer of a substrate, such as a carbon layer having hydrogen atoms bonded at the surface, in a plasma chamber to covalently bond carbon-flourine groups such as CF.sub.3 groups to carbon atoms in the surface. After establishing a plasma process in which both etching and deposition are ocurring, a fluorinated gas is injected into the chamber to allow CF.sub.3 groups to bond to the surface. The process does not apply of a layer with a defined thickness, but rather conditions the surface for desired properties of high affinity for lubricants and low affinity for contaminants. The invention is particularly useful for heads and disks for use in magnetic recording.
摘要:
We disclose a bi-layer wear pad, for use in a slider/magnetic media interface, comprising a wear layer and an adhesion layer. The wear material is either carbon or a carbonaceous material. Typical carbonaceous materials useful for wear layers include elements such as hydrogen, fluorine, nitrogen, boron, and silicon dioxide. The adhesion layer is a thin cermet such as nichrome oxide (NiCrOx) or chromium silicon oxide (CrSiOx). Use of the cermet adhesion layer allows a relatively thick wear layer to be deposited with good adhesion and superior durability.

A head slider for use in a disc drive data storage system includes a slider body substrate having a cavity formed therein. A transducer is positioned in the head slider such that walls of the cavity in the slider body substrate protect the transducer from contact with asperities on a surface of a data storage disc.

A magneto-resistive effect type head is provided to suppress the thermal asperity caused by projections or foreign matter found on the recording medium. A step or a protrusion which is closer to the recording medium than the element is provided on the air bearing surface of the head in an area on the leading side of the element with respect to the moving direction of the head.
