Abstract: 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.

Abstract: A magnetoresistive data writer and reader may be generally configured at least with a magnetoresistive (MR) element contacting a magnetic shield that is constructed of (Ni78Fe22)99.8O0.2 material. The magnetic shield may be formed with an electrodeposition process that uses ?-diketones derivatives to form nano-crystalline grain structure after a subsequent annealing at temperatures above 400° C.
