Abstract
A slider is used in an actuation system and carries a transducing head for transducing data to and from a rotatable recording disc. The slider includes a slider body having a leading edge and a trailing edge and a transducing head positioned proximate the trailing edge of the slider body. An encapsulant comprised of a self assembled monolayer covers exposed surfaces the slider body.

An improved actuation system for positioning a slider carrying a transducing head, the actuation system of the type having a movable actuator arm, a head suspension, a microactuator, a flexure, a slider and a transducing head carried by the slider, the improvement comprising:
- an encapsulant comprised of a self assembled monolayer covers exposed surfaces of a component selected from the group consisting of the microactuator, the slider, a disc spacer, surface mount components on a printed circuit card assembly, and ceramic components of the actuation system.
A slider comprising:
- a slider body having a leading edge and a trailing edge;
- a transducing head positioned proximate the trailing edge of the slider body;
- and
- an encapsulant comprised of a self assembled monolayer covering exposed surfaces the slider body.
A microactuator comprising:
- a first piezoelectric element attached between a mounting block and a suspension, the first piezoelectric element being deformable in response to a voltage applied thereto;
- an encapsulant comprised of a self assembled monolayer covering exposed surfaces of the first piezoelectric element;
- and
- a compliant joint between the mounting block and the suspension, the compliant joint being flexible to permit movement of the suspension with respect to the mounting block.
