    摘要: The invention is a perpendicular magnetic recording write head with a write pole, a trapezoidal-shaped trailing shield notch, and a metal gap layer between the write pole and notch. The write pole has a trailing edge that has a width substantially defining the track width and that faces the front edge of the notch but is spaced from it by the gap layer. The write head is fabricated by a process than includes reactive ion beam etching of a thin mask film above the write pole to remove the mask film and widen the opening at the edges of the write pole. The gap layer and notch are deposited into the widened opening above the write pole. The write pole has nonmagnetic filler material, such as alumina, surrounding it except at its trailing edge, where it is in contact with the gap layer, which is formed of a different material than the surrounding filler material.

    摘要: An optical lapping guide for determining an amount of lapping performed on a row of sliders in a process for manufacturing sliders for magnetic data recording. The optical lapping guide is constructed with a front edge that is at an angle with respect to an air bearing surface plane ABS plane, such that a portion of the lapping guides is in front of the ABS and portion of the lapping guide is behind the ABS. As lapping progresses, an increasing amount of the lapping guide will be exposed at the ABS and visible for inspection. Therefore, after a lapping process has been performed, the optical lapping guide can be inspected to determine the amount of material removed by lapping. The greater the amount of the lapping guide that is exposed and visible, the greater the amount of material removed by lapping.

    摘要: A multi-step process for notching the P1 pole of the write head element of a magnetic head. In a first step following the fabrication of the P2 pole tip, a layer of protective material is deposited on the approximately vertical side surfaces of the P2 pole tip. Thereafter, a first ion milling step, utilizing a species such as argon, is performed to mill through the write gap layer and to notch into the P1 pole layer therebelow. The removal of redeposited material from the side surfaces of the P2 pole tip is thereafter accomplished and the protective material formed on the side surfaces of the P2 pole tip protects the P2 pole tip during the redeposition clean up step. Thereafter, the protective material is removed from the side surfaces of the P2 pole tip, and a second ion milling step is performed to further notch the P1 pole material.
