摘要： 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.

摘要： An apparatus comprising a magnetic head suspension assembly (10) comprised of a rectangular portion (12), load beam (14) and flexure (16) fabricated from a silicon structure using the etching techniques of the integrated circuit fabrication industry. Said magnetic head suspension assembly (10) having electrical leads (23) to a slider, a pre-amp circuit (25) and a microactuator (27) fabricated directly thereon. A system of providing a loading force passing to slider (50) comprising either a tapered base plate (40) adapted to be held by a horizontally oriented actuator arm or an actuator arm (60) having at least one angled receiving surface (62,64) for attachment to said suspension assembly. The method of forming a magnetic head suspension assembly (10) from an etched silicon structure comprising a cutting step comprising cutting said silicon structure into the silhouette shape of a magnetic head suspension assembly, having a rectangular portion (12), a load beam (14) and a flexure (16), said flexure being cut in a shape such that finger members (18), slider bond tongue (19) and dimple tongue (20) appear thereon, and subsequent to said cutting step, the step of photo-etching regions of said silicon structure to reduce thickness of said silicon structure in certain regions, said photo-etching leaving a remaining non-etched small plateau area which is adapted to act as a point or dimple for an attached slider to gimbal about.

The method of forming a magnetic head suspension assembly (10) from an etched silicon structure comprising a cutting step comprising cutting the silicon structure into the silhouette shape of a magnetic head suspension assembly, having a rectangular portion (12), a load beam (14) and a flexure (16), the flexure is cut in a shape such that finger members (18), slider bond tongue (19) and dimple tongue (20) appear thereon. Subsequent to the cutting step, photo-etching regions of the silicon structure reduces thickness of the silicon structure in certain regions. The photo-etching leaves a remaining non-etched small plateau area which is adapted to act as a point or dimple for an attached slider to gimbal about.
