Materials for near field transducers and near field transducers containing same

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.

Formation of non-magnetic grooves

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 (NiFe)Omaterial. The magnetic shield may be formed with an electrodeposition process that uses &#x3b2;-diketones derivatives to form nano-crystalline grain structure after a subsequent annealing at temperatures above 400&#xb0; C.

A magnetic writing pole writes perpendicularly to a magnetic medium. The writing pole includes a multilayer structure with alternately electroplated magnetic layers and electroplated non-magnetic layers. The writing pole has a down-track thickness near the magnetic medium of less than about 500 nm.

Magnetic writer including an electroplated high moment laminated pole

A magnetic head for use in magnetic data storage systems is provided. The magnetic head includes a substantially non-magnetic writer gap layer and pair of magnetic poles separated by the writer gap layer. A first of the poles includes a first layer formed of a CoNiFe alloy that has a saturation magnetic moment greater than 2.1 Tesla. Methods of fabricating such a head are also disclosed.

Electrodeposited high-magnetic-moment material at writer gap pole

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 Fe Co Ni , 1.8 Tesla Fe Ni Co Tesla Fe Cr , or 1.9 Tesla Fe Co Cr , wherein the subscripts indicate a preferred range of atomic percentages for each element in the given alloy.
