摘要:
A micro-electromechanical systems (MEMS) disc drive includes high-precision and integrated components to allow for increased functionality, robustness and reduced size as compared to currently produced disc drives. Integrating multiple subcomponents of the disc drive using batch processing provides low manufacturing costs. Furthermore, using MEMS techniques, new features can be added to disc drives. For example, an environmental control component, an accelerometer and/or a thermometer may be integrated into the housing of the disc drive.

A transducing device responsive to magnetic fields includes a writer, a reader, an actuator, and a void. The actuator is positioned proximate the writer and reader. The void is positioned between at least one of the reader and writer and a substrate of a sensing device. The void is also positioned proximate an external surface.

A head for a data storage device including an independently supported transducer body floatably coupled to the slider body and including at least one transducer element. The transducer body is independently supported relative to the disc surface to provide transducer level control for read-write operations.

A transducer-level microactuator selectively positions a transducer portion of a slider radially with respect to circumferential data tracks of a rotatable disc. The slider includes a slider body having a leading edge and a trailing edge, a transducer body and a flexure body. The transducer body is spaced from the trailing edge of the sliding body and includes at least one transducer element. The flexure body extends from the trailing edge of the slider body and includes a first anchor point connected to the slider body and a second anchor point connected to the transducer body. The basecoat layer is deposited on the trailing edge of the slider body and substantially surrounds the flexure body wherein a gap separates the flexure body from the basecoat. A first actuation assembly is formed on the basecoat and a second actuation assembly is formed on the transducer body adjacent the slider body.

A method is used for fabricating sliders for use in a disc drive actuation system, the sliders having bonds pads formed on either a top surface or side faces of the slider. The method comprises providing a substrate having a top surface. Trenches are formed in the substrate and filled with a bond pad material to form slider bond pads. Excess bond pad material is removed from the trenches such that the slider bond pads are flush with the top surface of the substrate. A transducer is fabricated on the top surface of the substrate. Finally, the slider bond pads are exposed.

A disc drive slider test system includes a support structure and a slider test socket carried by the support structure that releasably electrically and mechanically receives a slider for testing. The slider test socket includes a body forming a cavity for receiving the slider and a plurality of spring beams outside a plan area of the body connected to a clamp for releasably securing the slider in the cavity. In some exemplary embodiments, a microactuator is employed to position the slider secured by the slider test socket with high resolution with respect to tracks of the disc.
摘要:
A slider for use in a disc drive system that is comprised of a trailing edge, a connection for applying a voltage to the slider, an actuation surface for providing electrostatic control, and a recessed area between the trailing edge and the actuation surface. Applying voltage to the slider provides a method for controlling fly height between the trailing edge of the slider and the disc.
摘要:
A method of improving the robustness of microcomponents formed of silicon by armor coating the microcomponent with a ductile material, such as a metal. The armored coating may comprise either partial armored coating or total armored coating. Providing the microcomponent with an armored coating reduces chipping and breaking, and likewise reduces contamination problems which arise from chips and breaks.

A slider assembly is operable to selectively alter a position of a transducing head with respect to a track of a rotatable disc having a plurality of concentric tracks. The slider assembly includes a slider wafer arranged to be supported by a disc drive support structure. A stator is bonded to the slider wafer, with the stator including at least one electrode. A rotor is bonded to the stator, with the rotor having a frame portion bonded to the stator and a head-carrying portion attached to the frame portion by a flexible beam structure. The head-carrying portion of the rotor carries the transducing head, supports at least one rotor electrode adjacent to the at least one stator electrode, and is movable with respect to the frame portion of the rotor in response to a voltage difference between the at least one rotor electrode and the at least one stator electrode.
摘要:
A method for filling a trench extending through a microelectromechanical system (MEMS) device patterned on a wafer is disclosed. The method involves simultaneously depositing a trench-fill layer of insulating material over a first side of the wafer, over a second side of the wafer, and into the trench extending from the first side to the second side. Further, the width of the trench at the first side of the wafer and/or the second side of the wafer is variable to adjust the rate at which the trench fills.
