RECORDING MEDIUM |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To suppress the crack occurrence resulting from the thermal stress when a garnet ferrite layer deposited on a substrate is annealed at high temperature. <P>SOLUTION: After the garnet ferrite layer is deposited on the substrate, a pattern made of unit elements with a suitable size by a photo lithography method etc. is formed. A recording layer with excellent perpendicular anisotropy is obtained, without cracks resulting from the thermal stress after high temperature annealing. <P>COPYRIGHT: (C)2007,JPO&INPIT |
