    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 magnetic write head for perpendicular magnetic recording having a write pole with a concave trailing edge. The magnetic write pole can have a trapezoidal shape with first and second laterally opposed sides that are further apart at the trailing edge than at the leading edge. The write head may or may not include a magnetic trailing shield, and if a trailing shield is included it is separated from the trailing edge by a non-magnetic write gap layer. The concave trailing edge improves magnetic performance such as by improving the transition curvature. A method for constructing the write head includes forming a magnetic write pole by forming a mask structure over a deposited write pole material, the mask structure having an alumina hard mask and an image transfer layer such as DURAMIDE®. An alumina fill layer is then deposited and a chemical mechanical polish is performed to open up the image transfer layer. A reactive on etch is performed to remove the image transfer layer and a reactive ion mill or reactive ion etch is performed to remove the alumina hard mask and form a concave surface on the write pole.

    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: Write elements and methods of fabricating magnetic write poles are described. For one method, a vertical mask structure is formed on a magnetic layer in locations of a pole tip and a yoke of a write pole. The vertical mask structure may be formed by coating vertical surfaces of resists with an atomic layer deposition (ALD) process or a similar process. A removal process is then performed around the vertical mask structure to define the pole tip and part of the yoke of the write pole, and the vertical mask structure is removed. A lower portion of the pole tip is them masked while the upper portion of the pole tip and the part of the yoke is exposed. The upper portion of the pole tip and the part of the yoke are then expanded with magnetic material, such as with a plating process.
