摘要： A method of mounting a magnetic head to a case employs a jig having a grooved placing unit for placing the head and a support for the case formed at a predetermined height from the slidably contacting surface of the head. The method includes placing the slidably contacting surface of the head on the bottom of the placing unit of the jig to position the head in the placing unit, placing the case on the support to set its height at a predetermined gap with respect to the mounting surface of the head, and filling a bonding agent in the gap between the mounting surfaces of the case and the head.

摘要： A magnetic head assembly of a disk drive device has an upper magnetic head fastened to a case side and a lower magnetic head mounted on a gimbal plate of a carriage side. The upper case assembly includes a plurality of leaf hinge springs extending to the vicinity of the upper magnetic head, which is bonded to a supporting plate, and wire leads from the magnetic head are soldered to the leaf hinge spring ends as lead terminals. The other ends of the leaf hinge springs extend to the rear side of the case and serve both as a pivotable hinge mounting of the case to the carriage and as lead terminals to an external read/write controller. The upper case assembly is formed by molding in resin a flat plate which is precut with the leaf hinge spring and supporting plate portions formed in a predetermined shape, cutting the flat plate thus insert molded to separate the plate and a plurality of lead terminals independently, fastening the upper magnetic head to the plate, and connecting the lead wires from the fastened magnetic head to the predetermined divided lead terminals. Thus, the magnetic head assembly can be accurately manufactured inexpensively.
