Magneto optical recording medium |
摘要 |
A magneto-optical recording medium in which information can be overwritten by a magnetic field modulation method, is provided with a magnetic thin film satisfying an inequality txMs<5 mu mxemu/cc wherein the film thickness is, represented by t mu m and the saturating magnetization is represented by Ms emu/cc. Even in the case where the intensity of the modulated magnetic field applied to the magneto-optical recording medium is small, a carrier to noise ratio C/N of not. less than a predetermined value and a jitter of not more than a predetermined value can be realized.
