    摘要： A transducer for magnetically reading and writing information is disclosed. The present invention eases the intricate process of wafer thin film deposition and bar lapping by proposing a transducer including a first and second member, both of which perform the reading and writing function of the transducer. The present invention provides a transducer with greatly improved magnetic efficiency by probing the media magnetization directly. The structure is inherently stable due to shape anisotropy of the members and the closure of magnetic flux at the ends of each member.

    摘要： A head assembly having a sensor element on the head assembly. Embodiments of the sensor element are configured to detect non-contact induced head-media interface instability, “onset of contact” or low level interference. The non-contact head-media instability or interference is detected based upon sensor feedback relating to excitation of the air bearing resonance modes of the slider body. In embodiments of the present invention, the sensor head assembly includes a microactuator which is energizable to microactuate the head or transducer elements on the head assembly.

    摘要： In an electrostatic actuator used to control fly height between a magnetic disc and a read/write head of a disc drive, a multi-layer electrode device is used. The multi-layer electrode device includes alternating insulating layers and conductive electrode layers. By controlling the material properties of each layer of the electrode device, problems associated with leakage current, field emission discharge, tunneling current, and slow actuator response time can be controlled.

    摘要： A method for forming a transducing head first requires the deposition of a bottom shield, a bottom thick gap, a bottom thin gap, a sensor, a first flux guide, a top thin gap, a top thick gap, and a top shield. After each of the layers is deposited, an air bearing portion of both the top and bottom thick gaps is removed, such that a length of the air bearing portion of the top thick gap is substantially equal to a length of the air bearing portion of the bottom thick gap. Next, an air bearing shield is deposited over the air bearing surface, the air bearing shield being in contact with the top and bottom shields, the top and bottom thick gaps, the top and bottom thin gaps, and the flux guide. Finally, the air bearing surface of the transducing head is planarized, resulting in the top and bottom thin gaps and the first flux guide each being exposed at the air bearing surface.
