Abstract
Magnetic films are annealed by radio frequency (RF) radiation. During the RF annealing process, the layers may be subjected to a magnetic field in order to control their anisotropy axes. The RF annealed layers are useful for applications such as longitudinal and perpendicular magnetic recording layers of magnetic data storage media.
Claims23
A method of annealing a layer of magnetic recording material, the method comprising:
- providing a layer of magnetic recording material;
- and
- annealing the layer with radio frequency radiation which inductively heats the layer of magnetic recording material.
