    摘要: A method of making a magnetic read/write head using a single lithographic step to define both a write coil and a pole tip structure. The use of a thin image resist layer over a hard reactive-ion etch mask and image transfer techniques allows very high resolution optical lithography which can accommodate formation of a very compact coil and pole structure. The use of a single high resolution lithography step on a planarized structure to define both a write pole tip and a write coil coplanar with the write pole tip avoids the problems of reflective notching associated with lithography to define the pole tip in the vicinity of non-planar features of the coil structure and also eliminates alignment inaccuracies inherent in separate lithography processes for the coil and pole.

    摘要: An embodiment of a magnetic head of the present invention includes a media heating device that is fabricated within the magnetic head structure following the fabrication of the read head element of the magnetic head. The media heating device is preferably fabricated between the first and second magnetic pole layers and close to the ABS surface of the head. The heating device includes electrical leads and an electrically resistive heating element that is preferably comprised of TaSiN, NiCr or NiFe, and in the present invention one or both of the magnetic poles are utilized as an electrical lead of the heating device. The heating device serves to heat the magnetic media immediately prior to the passage of the magnetic media beneath the pole tip, which lowers the localized coercivity of the media and facilitates the writing of data to the media by the write head element of the magnetic head.

    摘要: A a method for fabricating a structure, such as a magnetic head, having two coplanar metallic features of different compositions, both deposited on their own seed layers. The features may be made tall relative to their widths (ie. have a high aspect ratio), and are also very closely spaced. Only a single high-definition, critically aligned photolithographic procedure is used to create the critical structures, avoiding any problem with aligning features produced by multiple procedures. The method is applied to the production of the write structure of a magnetic read/write head, where a portion of the pole structure and the inductive coils are fabricated in the same plane with a close spacing and both having a vertical aspect ratio of more than about 2:1.

The read sensor is formed in the central region such that the first edge of the read sensor is disposed above an edge of the first bias layer and the second edge of the read sensor is disposed above an edge of the second bias layer. Third and fourth bias layers are deposited adjacent the read sensor. Methods taking different approaches are also presented.
