ABSTRACT:
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.
