| 摘要 |
The present invention provides a highly reliable patterned medium without generating an error in recording and reproduction, and a magnetic disc memory device using the same. The patterned medium has a substrate, a soft magnetic layer, a non-magnetic layer, an intermediate layer and a recording layer. The recording layer has a pattern structure of a non-magnetic material and a magnetic material, and the Young's modulus of the non-magnetic material is larger than the Young's modulus of the magnetic material.
