Abstract
Official abstract text for this publication.
The embodiments disclose a patterned composite magnetic layer structure configured to use magnetic materials having differing temperature and magnetization characteristics in a recording device, wherein the patterned composite magnetic layer structure includes magnetic layers, at least one first magnetic material configured to be used in a particular order to reduce a recording temperature and configured to control and regulate coupling and decoupling of the magnetic layers and at least one second magnetic material with differing temperature characteristics is configured to control recording and erasing of data.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for fabricating a patterned composite structure, comprising: creating a patterned composite magnetic layer structure in at least one stack feature of a recording device, wherein the patterned composite magnetic layer structure includes plural magnetic layers; using different magnetic materials having differing temperature and magnetization characteristics for the magnetic layers; and selectively raising and lowering temperatures of the patter…
