    摘要: A slider for attachment to a flexure of a disc drive system includes a slider body, a transducing head formed on the trailing edge of the slider body, and a microactuator formed on the leading edge of the slider body. The microactuator engages the flexure to rotate the transducing head in response to control signals applied to the microactuator. The slider is applicable to achieve fine positioning of the transducing head in a disc drive having an actuator arm supporting the flexure and a motor operable to move the actuator relative to a disc to coarsely position the transducing head. The microactuator and the transducing head may be formed by thin film deposition.

    摘要: A gimbal for supporting a slider at its leading surface in a disc drive assembly includes a gimbal body, a slider support beam and a slider mounting tab. The slider support beam is carried by the gimbal body and defines a vertical slider alignment feature. The slider mounting tab extends out of plane from the slider support beam and defines a horizontal slider alignment feature. The slider mounting tab is attached to the leading surface of the slider. The design of the slider mounting tab of the present invention is useful for supporting a leading edge microactuator at a leading edge of the slider for micropositioning a transducer over ideal track centers on a disc surface.

    摘要: An air bearing slider for a disc drive includes an air bearing surface defined on the disc opposing face at least in part by a first step or cavity. An additional corner step is defined in bar processing, deeper than the first cavity. With the corner step, the first cavity does not extend quite all the way to the corner of the slider. The corner of the slider, formed on one face by dicing of the bar into individual sliders, is at an additional depth due to the corner step. The corner steps are preferably narrow, such as nominally one to two times the tolerance value on the dice cut. If a shock event occurs which causes the air bearing slider to contact the disc at certain roll and pitch angles, the corner step edge will contact the disc rather than the dice cut corner. The corner step thus lessens the probability of contact between the disc and the corners of the air bearing slider, and contact with a dice cut edge of the slider is avoided. This reduces the amount of damage to the disc drive caused by the shock event.
