Abstract
A method and apparatus for collocating an interface circuit with a disk drive read/write head is described. In one embodiment the interface circuit is attached to the load arm on one side and the miniflex interconnect on the other. The read/write head is mounted on the miniflex directly below the interface circuit. The interface circuit comprises a read signal preamplifier, a write driver, and head selection circuitry. A common multiplexer circuit is used to perform the other conventional read/write circuit functions. The common multiplexer circuit includes a head selection block to determine which heads are activated, a head driver block, and a read receiver block. The common multiplexer circuit is mounted at the base of the miniflex.
