Abstract: YO986-013 MICRO MECHANICAL ACTUATED TRANSDUCER HEAD ON A SLIDER A micro-mechanical actuated transducer head on an air bearing slider is disclosed herein. The transducer head is made to move relative to the slider assembly by the incorporation of an actuating material intermediately to the slider assembly and head. The actuating material can be: electromechanical, piezoelectric, electrostrictive, thermal, pneumatic, or hydraulic. The actuating material can be incorporated either integral to the head/slider assembly or made to bridge the slider to head attachment. With the incorporation of said actuatable material, said head can be moved micro-mechanically relative to said slider effecting relative and controllable motion either horizontally and/or vertically.

Abstract: A magnetic transducer and suspension assembly suitable for use in both contact recording and in winchester-type applications is described. A generally rectangular elongated flat suspension member includes a vertical-type inductive read/write transducer formed integrally with the suspension member and is embedded in one end of the suspension member. The vertical inductive transducer is suitable for vertical recording applications. The transducer vertical magnetic pole tip and magnetic yoke structure are formed at one end of the suspension member with the vertical pole tip extending to and exposed at an air bearing surface formed on the lower surface of a slider-shaped protrusion extending from the lower surface of the end of the suspension member. The integral transducer/suspension assembly can be adapted for either flying above the recording media or for use in continuous contact with the recording media. The air bearing surface is formed on the lower surface of a wear pad. The fabrication of the transducer/suspension assembly is adapted to be performed at the wafer level.

Abstract: PULSED CURRENT RESISTIVE HEATING FOR BONDING TEMPERATURE CRITICAL COMPONENTS Controlled current pulses applied to a shaped resistive heating element formed on the bonding surface of a base or substrate component provide sufficient heat to the bonding interface formed between a ship and the base bonding surface to produce a high bonding temperature at the bonding interface while maintaining an opposite surface of the chip at or below a relatively low temperature critical for components formed or mounted on the chip surface. A layer of a thermally setting thin-film bonding agent is applied over a serpentine-shaped resistive heating element having a relatively narrow linewidth formed on the base component bonding surface. The chip to be bonded is retained in a desired position against the bonding surface over the heating element and bonding agent layer while a current pulse is applied to the heating element via contact pads. The current pulse magnitude and duration are controlled to produce sufficient local heating at the bonding interface to effect the desired bonding without excessive heating of any critical components at some predetermined distance from the bonding site.
