    摘要: The present invention generally relates to fabricating a bond pad for electrically connecting a laser diode to a slider and a TAR head in a HDD. The bond pad is deposited on a surface of the head that is perpendicular to the air bearing surface (ABS). The head is diced and lapped to expose the bond pad on a top surface of the head and mounted on a slider. The laser diode and a sub-mount may be coupled to the top surface of the slider—i.e., the surface opposite the ABS—by connecting to the bond pads. Specifically, both the laser diode and the sub-mount have electrodes thereon that are perpendicular to the bond pads. Conductive bonding material is used to bond the laser diode and the sub-mount to the bond pads.

    摘要: A perpendicular magnetic recording write head has a flux conductor in contact with the write pole. The flux conductor is substantially wider than the write pole tip in the cross-track direction and has a blunt end that is recessed from the pole tip end. The region of the flux conductor where its blunt end is in contact with the pole tip is the “choke” point for the write pole, i.e., the point where the flux density is highest. The flux conductor enables the write pole to be made with no flare, or with a flare angle and throat height with a much wider tolerance, which substantially simplifies the manufacturing process. The write head may have a trailing shield and side shields that substantially surround the write pole tip and remove stray fields that may be produced by the flux conductor, so that regions of the recording layer other than the track being written are not adversely affected.

    摘要: A method for forming a perpendicular magnetic recording head using an air-bearing surface damascene process and perpendicular magnetic recording head formed thereby is disclosed. The perpendicular head is formed by depositing a pseudo trailing shield layer over a pole layer and selectively etching the pseudo trailing shield layer to a depth equal to a desired trailing shield throat height. Then, a magnetic material is deposited in the resulting void.

    摘要: A thin-film write head employing pole pieces formed of an electroplated body-centered cubic (BCC) nickel-iron alloy with a saturation flux density (BS) of 1.9 to 2.3 T (19 to 23 kG) and an acceptable coercivity (HC) of about 80 to about 160 A/m (1-2 Oe). The iron content of the electroplated nickel-iron alloy is from 64% to 81% by weight. The two-layer pole fabrication process holds magnetic anisotropy and coercivity to useable values while improving saturation flux density and optimizing magnetostriction. This is accomplished by first electroplating a BCC nickel-iron layer onto an underlying seed layer and then annealing the two layers to reduce coercivity to less than about 160 amps/meter and raise magnetization to acceptable levels.

    摘要: A magnetic head assembly has an open yoke type write head constructed on top of a read head so that the write head can be constructed with a very narrow track width without restraint by the requirements of the read head. The write head has first and second pole piece portions wherein the second pole piece portion has separate front and back layer portions. A coil layer is wrapped around only the first pole piece portion and the back layer portion so that the front layer portion can be constructed separately to provide a narrow track width. Further, in a preferred embodiment the front layer portion has a reduced thickness and a higher magnetic moment than the thickness and magnetic moment of the first pole piece portion and the back layer portion. Still further, in a preferred embodiment the first pole piece portion and the back layer portion are planar due to polarization of underlying layers.
