| Abstract: | This paper reports the dynamic read/write properties of magneto-optical (MO)disks having an AIN/TbFeOo/AlN/Al multilayer structure. When the recording bit size is 1 um, the value of carrier to noise ratio (0/N) of MO disks exceeds 45 dB. This paper also discusses some reasons which affect 0/N, according to the measured results. |

| Keywords: | magneto-optical disk carrier to noise ratio co-sputtering eccentricity. |
