摘要:
A perpendicular media is formed without an adhesion layer between the substrate and soft underlayer (SUL) to reduce the cost of fabrication. The thickness of the SUL is reduced to less than 50 nm to increase the film adhesion strength between the substrate and SUL. The perpendicular media comprises only a substrate, the SUL, an exchange break layer, a recording layer, and a protective overcoat.
摘要:
A system, method and computer program product for a user to verify that a network resource address is trusted. At least one entity registration is stored at a server. Each entity registration comprises an identity of an entity and entity addressing information associated with the identity of the entity. The existence of at least one entity whose identity is included in the at least one entity registration is confirmed. A query comprising a target addressing information is received from a client. If the target addressing information matches the entity addressing information, the identity of the entity associated with the entity addressing information is determined and a result comprising the identity of the entity associated with the entity addressing information matching the target addressing information is transmitted to the client. If no entity addressing information matches the target addressing information, an indication of such is transmitted to the client.

A method for a down hole cutting tool is disclosed, wherein the cutting tool includes a cutting element support structure having at least one cutter pocket to support a cutting element comprising a substrate and an ultrahard layer. The method includes inserting a base portion of the cutting element into the cutter pocket; locating a first braze alloy such that when heated the first braze alloy melts and fills a space in the cutter pocket between the cutting element and the cutting element support structure adjacent the ultrahard layer; locating a second braze alloy such that when heated the second braze alloy melts and fills a space in the cutter pocket between the cutting element and the cutting element support structure non-adjacent the ultrahard layer; and heating the first and second braze alloy such that they melt.

The exemplary embodiment of the present invention provides a storage buffer management scheme for I/O store buffers. Specifically, the storage buffer management system as described within the exemplary embodiment of the present invention is configured to comprise storage buffers that have the capability to efficiently support 128 byte or 256 byte I/O data transmission lines. The presently implemented storage buffer management scheme enables for a limited number of store buffers to be associated with a fixed number of storage state machines (i.e., queue positions) and thereafter the allowing for the matched pairs to be allocated in order to achieve maximum store throughput for varying combinations of store sizes of 128 and 256 bytes.
摘要:
A lubricant composition is provided comprising a first liquid lubricant and a second liquid lubricant, wherein the first liquid lubricant contains a cyclotriphosphazene ring attached to at least one perfluoropolyether having a single terminal hydroxyl group, and the second liquid lubricant contains a perfluoropolyether having two end groups selected from hydroxyl, tertiary amine, and combinations thereof. A magnetic recording media is also provided, comprising a substrate, a magnetic layer, an overcoat layer and a lubricant layer thereon, wherein the lubricant layer is formed from the lubricant composition. A further aspect of the invention concerns a method of making a magnetic recording media comprising forming a magnetic layer on a substrate; forming a protective overcoat layer on the magnetic layer; and forming a lubricant layer on the surface of the overcoat layer by applying the lubricant composition to the surface of the overcoat layer. The lubricant composition is useful for magnetic recording media, especially for magnetic storage hard disk drives, and provides improvements such as substantially reduced lubricant thickness variations when applied to a surface of a hard disk drive.
