摘要： An improved magnetic shield for a perpendicular magnetic write head is disclosed. Its main feature is a pair of tabs at the shield's bottom corners. Said tabs are significantly wider at their point of attachment to the shield than further away from the shield. The end portions of each tab slope upwards (away from the ABS) at an angle of about ten degrees. A process for manufacturing the shield is also disclosed.

摘要： A perpendicular magnetic recording (PMR) head is fabricated with a multi-level tapered write pole. The write pole comprises a main pole with a tapered tip on which is formed at least one yoke that has a tapered edge. The edge of the yoke is recessed from the ABS of the tapered tip, giving the write pole a stepped profile. The tapered tip can be two sloped surfaces that are symmetric about a mid plane of the main pole or the taper can be a single sloped edge on the leading side or the trailing side of the pole. The yoke structure can consist of a single yoke formed on one side of the main pole or it can consist of two yokes formed symmetrically on both the leading and trailing sides of the main pole. Other yoke/pole combinations are also described as are various shield formations. The write pole structure creates an efficient channeling of magnetic flux to the ABS surface of the pole tip which produces magnetic recording field at high area densities.

摘要： A basic design is disclosed for bottom shield (S1) and top shield (S2) of the reader shields in a magnetic read-write head. The critical part of new design includes an antiferromagnetic film which pins an antiferromagnetically coupled trilayer (AFCT). The simplest embodiment for top shield, for example, would be a film sequence of FM/Ru/FM/AFM. This replaces the normal top shield design which typically comprises a ferromagnetic seed layer and a thicker plated ferromagnetic film. Processes for manufacturing these shields are also described.

摘要： A perpendicular magnetic recording (PMR) head is fabricated with a pole tip shielded laterally by a pair of symmetrically separated side shields that extend from an edge of a trailing edge shield to form a shield with the shape of a π. The easy axis direction of the side shields is in the in-track direction. As a result, the side shields effectively shield the fringing fields of the magnetic pole tip from causing adjacent track erasures, while not adding their own fringing fields that could cause erasures even beyond adjacent tracks.

摘要： A sloped reader is disclosed that reduces skew between reader and written transitions in shingled writing. The reader is formed between surfaces of S1 and S2 shields that are aligned parallel to the sloped reader. A PMR writer is described that straightens transition curvature and reduces signal-to-noise ratio in shingled writing. In one embodiment, a symmetrical writer with a bowed trailing edge where two corners have a greater pole height than a center portion may be used for either right corner or left corner shingled writing. In a second embodiment, an asymmetrical writer is formed with a straight and sloped trailing edge such that the write corner has a greater pole height than the opposite corner on the trailing edge. The bowed angle in the symmetrical writer and slope angle in the asymmetrical writer is between 5 and 45 degrees and preferably between 10 and 30 degrees.
