摘要:
A reader formed in a data transducer includes a first shield, a read gap, a second shield, a maanetic compensation layer, and a non-magnetic spacer layer. The first shield is formed of a multilayer comprised of a layer of a first material. The second shield is spaced apart from the first shield by the read gap. The magnetic compensation layer is formed in the first shield and has a coefficient of thermal expansion of less than the coefficient of thermal expansion of the first material. The non-magnetic spacer layer separates the first material layer and the compensation layer of the first shield.
摘要:
A method is disclosed for defining discrete magnetic and non-magnetic regions on the magnetic film layer of a storage media substrate. The method applies anodic oxidation of a cobalt-containing magnetic film layer to remove cobalt, followed by controlled deposition of a non-magnetic matrix into the regions where the cobalt has been removed. Deposition may either be electrodeposition, collimated vacuum deposition, or other methods depending upon the composition of the non-magnetic matrix being deposited. The method may be performed in a single electrochemical cell.
