    摘要： A magnetic write pole having a structure that prevents thermally induced pole tip protrusion. The write head has a return pole with a magnetic pedestal formed at the air bearing surface (ABS) and a back gap at an end opposite the ABS. An electrically conductive write coil having a plurality of turns passes over the return pole. A fill layer of a material having a low coefficient of thermal expansion, such as alumina is disposed between the coil and the pedestal, and may extend over the top of the coil to the back gap. A photoresist coil insulation layer may be provided between the turns of the coil to insulate the turns of the coil from one another. The photoresist coil insulation layer can also extend to the back gap. A write pole, formed above the return pole and coil is magnetically connected with the back gap layer and return pole by a magnetic shaping layer.

    摘要： The structure for a narrow pitch tape head array is disclosed. Narrow pitch is obtained by offsetting the location of the write gaps of successively stacked coplanar head arrays. A compact structure with lower fabrication cost is obtained by sharing magnetic pole layers between the stacked co-planar arrays.

    摘要： The present invention is an integral magnetic head suspension and method for making the same. The integral suspension, with or without the head, contains integrated conductive circuits that have multiple cross overs for noise reduction. The suspension is fabricated completely on silicon (Si) wafers using semiconductor processes. A N+ silicon layer is disposed over a P- silicon wafer. The N+ silicon layer and the P- silicon water are thermally oxidized to generate a bottom silicon oxide layer opposite the N+ layer side of the wafer and a top silicon oxide layer on the N+ side of the wafer, and to drive the N+ silicon into the P- silicon wafer. A layer of polysilicon is disposed over the silicon oxide layer on top of the N+ silicon layer. One or more pairs of conductive traces having multiple cross-overs are fabricated on the layer of polysilicon. Optimally, a magnetic head is simultaneously fabricated on the suspension. The polysilicon layer is then patterned to define the head structure and suspension structure as one piece. Finally, the magnetic head and suspension are separated from the wafer by removing the first silicon oxide layer by a chemical etchant and the P- silicon wafer by selective etching. The head and suspension are released from the silicon wafer as a single structure using the above-described semiconductor processes. Accordingly, no grinding or cutting is used to define the dimensions of the head. Further, no processes are required to attach the head to the suspension and the suspension can be made from low mass materials such as silicon (Si) or Al.sub.2 O.sub.3.
