    摘要： A disc drive has a recording disc rotatable around an axis, a slider supporting a transducing head for transducing data with the disc, and a dual-stage actuation assembly supporting the slider to position the transducing head adjacent a selected radial track of the disc. The dual-stage actuation assembly includes a movable actuator arm, a suspension assembly supported by the actuator arm and including a flexure, a tongue supporting the slider, and a microactuator. The microactuator includes a rotor attached to the tongue and a stator attached to the flexure and operatively connected to the rotor to radially move the rotor with respect to the stator. At least one beam is attached between the slider bond pad and the stator.

    摘要： A process of forming a microactuator for positioning a transducing head over a selected radial track of a rotatable disc in a disc drive system is disclosed. A tub is etched in a substrate, and a bottom coil layer is plated at least partially in the tub. A first insulating layer is deposited on the bottom coil layer. A ferromagnetic core layer is formed on the first insulating layer. A second insulating layer is deposited on and around the ferromagnetic core layer. A top coil layer is plated on the second insulating layer, and contacts the bottom coil layer at a point spaced from the ferromagnetic core. A rotor is formed on a rotor substrate to confront the ferromagnetic core, is operatively attached to the slider and is movable with respect to the ferromagnetic core.

    摘要： A microactuator for radially positioning a transducing head over a selected radial track of a rotatable disc in a disc drive system having a flexure to support a slider carrying the transducing head includes a stator operatively attached to the flexure. First and second pole pieces are substantially parallel to and spaced from each other, each having first and second ends. A via magnetically connects the first and second pole pieces. The first and second pole pieces are shaped so that a first gap between the first end of the first pole piece and the first end of the second pole piece is smaller than a second gap between the second end of the first pole piece and the second end of the second pole piece. A plurality of coils are wrapped around the stator. A rotor confronts the second end of the first pole piece and the second end of the second pole piece. The rotor is operatively attached to the slider and is movable with respect to the stator in response to an electrical current applied through the coils, so that movement of the rotor alters a radial position of the transducing head with respect to the flexure.

    摘要： A disc head slider (36) includes a slider body with leading, trailing, inside and outside slider edges (50,52,54,56) and a slider center line (58) extending from the leading slider edge (50) to the trailing slider edge (52). First and second raised side rails (60,62) are formed in the slider body and each include an inside rail edge (108), an outside rail edge (110), a leading rail edge (50) and a trailing rail edge (112). The first and second raised side rails (60,62) form first and second bearing surfaces (70,72), respectively, which terminate prior to the trailing slider edge (52). A raised center rail (64) extends along the slider center line (58) and between the first and second raised rails (60,62). First and second cavities (80a,80b) are positioned between the raised center rail (64) and the first and second raised rails (60,62), respectively. The first and second bearing surfaces (70,72) each include a leading section (100), a waist section (104), a leg section (102) which extends from the waist section (104) to the leading section (100), and a trailing section (106) which extends from the waist section (104) to the trailing rail edge (112). The trailing section (106) widens from the waist section (104) toward the trailing rail edge (112) and includes a notch (113) positioned along the inside rail edge (108) which narrows the trailing section (106) at the notch (113).

    摘要： The present invention provides an emergency starting device, including a first output end and a second output end, wherein the first output end is used for being connected to a positive electrode of an accumulator battery in an engine starting system and the second output end is used for being connected to a negative electrode of the accumulator battery; the device includes a super-capacitor, a controller and a DC-DC booster circuit, wherein the controller receives first electrical signal from the accumulator battery and electrically connects the super-capacitor and the accumulator battery to start the engine with energy stored in the super-capacitor when the first electrical signal changes suddenly, the DC-DC booster circuit increases the output voltage of the accumulator battery to charge the super-capacitor. The invention further provides an emergency starting method accordingly. By using the super-capacitor, the controller and the DC-DC booster circuit the invention fits in various severe environments and can start an engine in emergency permanently and effectively.
