ABSTRACT:
A base plate is disclosed for swage or ball stake mounting a transducer carrying arm to a support arm. The base plate includes a flange and a tubular member or boss. The flange has a non-rectangular profile and first, second, third and fourth arms extending generally in first, second, third and fourth directions. Each of the arms of the flange defines a separate corner of a rectangular profile so that rectangular profile compatible equipment can be used with the base plate of the present invention. The non-rectangular profile of the flange fits within the defined rectangular profile such that the mass of the flange is reduced to thereby improve resonance, shock and access time performance of the disc drive.
