Abstract: For PMR (Perpendicular Magnetic Recording) design, one of the major technology problems is the use of CMP to fabricate the pole structure. If the device is under-polished there is a danger of leaving behind a magnetic shorting layer while if it is over-polished there may be damage to the main pole. This problem has been overcome by surrounding the main pole, write gap, stitched write head pillar with a layer of CMP etch stop material which, using optical inspection alone, allows CMP (performed under a first set of conditions) to be terminated just as the stitched write head gets exposed. This is followed by a second CMP step (performed under a second set of conditions) for further fine trimming of the stitched head, as needed.

Abstract: A rolled steel plate 1 wound in a roll shape is unrolled and is cut in given dimensions to form a blank 2. In this case, a cut surface 2a is caused to incline at 1 to 3 degrees relative to the thickness direction of the blank 2, wherein the inclination direction of the cut surfaces 2a, 2a on each side is reversed. The blank 2 cut in this manner is roll-formed to cause the cut surfaces 2a, 2a to confront each other. Since the cut surfaces 2a, 2a on each side incline at 1 to 3 degrees in the opposite direction as described above, the cut surfaces 2a, 2a are caused to be parallel. Then, the confronting sections are laser-welded to form a cylindrical body 3.

Abstract: A method of creating fingerprint-imprinted jewelry which includes the steps of applying a lubricating oil to a fingertip and providing an amount of precious metal clay sufficient to generally cover at least a portion of a fingertip. The amount of precious metal clay is then formed into a fingerprint-receiving shape such as a generally flat disk or plate and a fingertip is then pressed into the precious metal clay such that a fingerprint of the fingertip is formed and retained on and within the amount of precious metal clay. The amount of precious metal clay is then air-dried to initially set and retain the fingerprint and then is fired within a kiln to ablate substantially all of the organic binding material within the precious metal clay thereby leaving only the precious metal having the fingerprint formed thereon which is thus available for use as a piece of jewelry.
