摘要： A disk for a hard disk drive. The disk includes a protective layer of shape memory alloy material over a magnetic layer. Contact between a head of the drive and the shape memory alloy material will cause frictional heat. The heat will cause a solid-solid phase transformation of the shape memory alloy material that will absorb energy and reduce wear. After head-disk contact terminates the shape memory alloy material will resume its initial solid phase. The shape memory alloy material may be relatively thin thereby improving the magnetic characteristics of the disks while providing a protective coating.

摘要： A magnetic data storage system having a scanning tip array based system and a shape memory thin film-based data storage medium. Prior to storing data, the medium is in its non-ferromagnetic austenitic phase. Indentation stress locally induces martensitic transformation of the medium, which in turn generates a locally ferromagnetized surface. By measuring the magnetic force interaction between the tip and the medium surface, inscribed magnetic information can be read. The shape memory thin film enables the stress-induced local magnetic transition to provide a fast data storage system with high data storage density.

摘要： A sputtering target forming method, a sputtering target, and a method of using a sputtering target are herein disclosed. Large area sputtering targets are necessary for producing films on large area substrates. To save on material costs, the large area sputtering target can be formed of multiple target tiles that can be placed adjacent each other on a backing plate. The gaps that are present between the target tiles may to be filled to ensure that the backing plate does not sputter and contaminate the sputtering process. The material filling the gaps may be of the same composition as the sputtering target tiles. Alternatively, the entire sputtering target can be plasma sprayed onto the backing plate to ensure that the sputtering target has a unitary sputtering target body across the entire large area backing plate.
