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.
摘要:
A magnetic recording head has a magnetic pole tip and a seed layer upon which the magnetic pole tip is formed. The seed layer is preferably formed of a high magnetic moment material having a saturation magnetization of at least 1.8 Tesla and a high resistance to corrosion. In preferred embodiments of the present invention, the seed layer is preferably formed of 2.1 Tesla Fe44-46Co39-41Ni14.5-15, 1.8 Tesla Fe54-56Ni27-29Co16-18 Tesla Fe86-90Cr10-14, or 1.9 Tesla Fe52-62Co26-36Cr10-14, wherein the subscripts indicate a preferred range of atomic percentages for each element in the given alloy.
