    摘要: A PMR writer is disclosed that includes a recessed center section in the write pole trailing edge and a center recessed trailing shield to improve the field gradient at track edge. In all embodiments, there is a non-uniform write gap between the trailing edge and the trailing shield. The recessed portion of the write pole trailing edge and/or center recess of the trailing shield has a thickness from 10 to 40 nm in a down-track direction and a width in a cross-track direction of 20 to 200 nm. The distance between the center recess and a corner of the trailing edge is from 20 to 80 nm. A sequence of steps is provided to fabricate the two embodiments of the present invention.

    摘要: A method of fabricating a magnetic recording medium sequentially forms a magnetic recording layer, a protection layer, and a lubricant layer on a stacked body. The lubricant layer is formed by vapor-phase lubrication without exposing the stacked body to atmosphere after forming the protection layer on the stacked body. A region having a gas pressure P3 is provided in a transport path of the stacked body after the formation of the protection layer and before the formation of the lubricant layer, satisfying relationships P3>P1 and P3>P2, where P1 denotes a process gas pressure at a time of forming the protection layer, and P2 denotes a process gas pressure at a time of forming the lubricant layer.

    摘要: A method and apparatus for forming magnetic media substrates is provided. A patterned resist layer is formed on a substrate having a magnetically susceptible layer. A conformal protective layer is formed over the patterned resist layer to prevent degradation of the pattern during subsequent processing. The substrate is subjected to an energy treatment wherein energetic species penetrate portions of the patterned resist and conformal protective layer according to the pattern formed in the patterned resist, impacting the magnetically susceptible layer and modifying a magnetic property thereof. The patterned resist and conformal protective layers are then removed, leaving a magnetic substrate having a pattern of magnetic properties with a topography that is substantially unchanged.
