ABSTRACT:
A magneto-optical disk system includes a magneto-optical disk and a disk drive. The magneto-optical disk drives provides a function of controlling the shape of a recorded domain by using a short wavelength laser beam and a test recording and a function of recording a using a pulse train. The magneto-optical disk has a laminated layer structure capable of obtaining a high S/N ratio and stabilizing a heat conduction. The magneto-optical disk drive with the recorded domain shape control function using a short wavelength laser beam and a test recording and with the pulse train recording record function is organically coupled with the magneto-optical disk having the laminated layer structure with a stabilized heat conduction to make the disk and the disk drive have an integrity therebetween, providing a magneto-optical disk having a recording capacity four times as large as the first generation magneto-optical disk system.
