摘要： A contact recording disk file uses an integrated head-suspension assembly having a head carrier with a dual-layer wear pad for contacting the disk during read and write operations. The outer wear layer of the pad is relatively soft and wear prone compared to a harder and more wear-resistant inner layer. The outer wear layer wears away at a relatively rapid rate during initial wear-in of the head carrier. In this manner the head pole pieces, which extend into the wear pad, are rapidly put into contact with the disk, thereby compensating for initial misalignment of the wear pad with the surface of the disk. The inner wear layer then provides wear resistance over the life of the disk file. In the preferred embodiment, both the outer and inner wear layers are formed of essentially amorphous carbon doped with different amounts of hydrogen.

摘要： A disk drive assembly in which the suspension and read/write transducer are integrated into a combination assembly and fabricated using thin film deposition techniques thereby producing an assembly which is very low in mass permitting contact recording. In one embodiment, transducers are deposited in a row and column configuration onto a release and support layer covering a wafer substrate having a thickness equal to a desired suspension length. The wafer is separated into a plurality of row sections, with each row section providing one thin film transducer from each column. A second release layer is formed on a separated side on the row section and thin layers of suitable materials are deposited to form a suspension layer including conductive lines extending to the thin film transducers. The first and second release layers are dissolved and the row section is further cut to form the individual combination assemblies. In a second embodiment, the wafer substrate has a thickness equal to the width of the suspension. The transducers deposited on a row are separated by the desired suspension length to produce combination assemblies useful for linear disk drive actuators. The excess portion of the wafer substrate can alternatively be removed by cutting or etching eliminating the requirement for release or support layers.
