Optical readout method with a direction of a magnetic field applied to a recording medium changed with a signal, and a system therefor |
摘要 |
An optical recording medium, optical recording method with use of it, and optical recording device for it comprise at least one magnetic layer on a substrate, the magnetic layer having a temperature Tco at which sizes of domains of the magnetic layer is sharply shrunk or expanded with temperature, thereby being capable of writing and reproducing high-density information formed of smaller domains than an optical spot diameter in a high signal quality.
