Magnetic data read/write apparatus is disclosed for use in connection with a magnetic data storage disk. The apparatus includes a read/write head mounted onto a positioning device along with several electrical leads that extend from the read/write head to an interconnect pad mounted on the positioning device. The interconnect pad includes an electrically-conducting layer divided into several separate conducting paths corresponding to the number of leads to the read/write head. A portion of each separate conducting path is exposed to facilitate electically-conducting connections to the read/write leads. Additional portions of each separate conducting path is exposed to facilitate electrically-conducting connections to other electrical connectors so as to obviate further manipulation of the leads to the read/write head. The apparatus further includes a flex cable structure having a conducting layer divided into several separate conducting paths corresponding to the conducting paths in the interconnect pad. A portion of each conducting path in the flex cable forms an electrically-conducting connection to one of the separate paths in the interconnect pad. The flex cable may further include a second conducting layer similarly divided into several separate paths with the two conducting layers of the flexible cable partially overlapping in a region configured to form a pre-amplifier circuit.

Computer disk head interconnect assembly

The head positioner for a Winchester type hard disk drive digital storage system includes a main rotating metal body portion having outwardly extending, integral, head positioning arms. The magnetic heads for reading and writing information on the hard disks are mounted on springy members which are referred to as 'load beams'. In order to reduce vibration, and to increase the accuracy of positioning of the heads on the disks, the outwardly extending arms from the main metallic body of the head positioner unit extend outwardly from the central axis of rotation for a distance which is substantially greater than the additional outward extent of the spring load beams upon which the magnetic heads are supported. Preferably the outward extent of the rigid arms is in the order of twice the length of the springy load beams. In addition, the bearings for supporting the rotating head positioning assembly are preferably mounted directly to the metallic body of the head positioner assembly. The springy load beams which support the magnetic heads may be secured to the ends of the outwardly extending arms by the placement of preformed exterior filler metal buttons over the holes in the ends of said load beams which join with said integral arms' tapered ends whereby a means for generating a solid phase metallurgical bond generates a solid phase metallurgical bond between said buttons and said integral arms thereby securing said load beams and the associated magnetic heads to said integral arms.
