Magnetic recording medium and method of fabricating the same |
摘要 |
A read-only disk and a write-only disk recorded at high density having a magneto-optical film differing in coercive force depending on the information to be recorded disposed on a substrate. In the read-only and write-once disks, signals can be read employing only part of the irradiation beam, and thus super-resolution reading is realized.
