Abstract: High density magnetic disk storage and semiconductor module technologies are combined to provide a disk drive using a standard multilayer ceramic substrate 10 as the disk drive base support member to support spindle 14 and actuator assemblies 25 including 1 inch diameter disks. The ceramic substrate has components and VLSI chips 40, 41 mounted directly thereon to avoid use of one level of packaging and presents standard pins 44 to mount the drive using standard sockets 45 to afford economy and reliability.

Abstract: A first thin film of appropriate texture, lattice constant, and crystal structure, such as body centered cubic vanadium or chromium with (110) texture is deposited upon a rigid or flexible substrate forming a plurality of polycrystals. A ferrite such as magnetite (Fe3O4) is sputtered from a target onto the first thin film forming a mixture of gamma Fe2O3 and Fe3O4 substantially completely without formation of Fe or other oxides of iron, providing good magnetic characteristics and resistance to corrosion. The substrate temperature can be maintained as low as 200 DEG C for both steps when sputtering or evaporation is employed.

Abstract: Elimination of crosstalk in an integrated array of magnetoresistive reading heads by the use of regions of high coercivity material between the active areas of closely spaced magnetoresistive sensors so as to prevent flux coupling between such closely spaced sensors.
