    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.

    摘要: The present invention is a magnetic head having a helical induction coil and includes hard disk drive devices that utilize the magnetic head. The helical coil is fabricated around a magnetic pole yoke in a series of process steps that include a reactive ion etch (RIE) process step which is utilized to simultaneously form vertical interconnect vias and upper helical coil member trenches. Thereafter, in a single fabrication step, such as by electroplating, the vertical interconnect lines and the upper helical coil traces are created in a single fabrication step, such that they are integrally formed. The vertical interconnect lines provide an electrical connection between outer ends of previously formed lower helical coil traces and outer ends of the integrally formed upper helical coil traces, such that a helical coil is fabricated. In the preferred embodiment, the helical coil is composed of copper.

    摘要: A write head has a second pole tip layer, a coil layer and a write coil insulation layer that are planarized at their top surfaces. A thin top insulation layer insulates the top of the coil layer from a yoke portion of the second pole piece which is connected to the second pole tip layer in the pole tip region and connected to a first pole piece layer in a back gap region. In a preferred embodiment the write gap layer extends throughout the yoke region and provides the only insulation between the first pole piece layer and the coil layer. Further, it is preferred that the write coil insulation layer be an inorganic material such as silicon dioxide (SiO2). Several embodiments of the write head are provided along with novel methods of making.

    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.
