“…The shape of the recorded domain is one of the important factors to improve the qual i ty of the reproduced signal. Unlike the case of the sensitivity, it is very hard to predict theoretically the conditions for the optimum shape of the recorded domains (8). This is because the bit formation process is a complex function of the magnetiza t ion and the coerc i ve force at the recording temperature.…”

Accurate servo-signal, good recording characteristics and sufficient signal-to-noise ratio are revealed to be necessary conditions for the optimum design of magneto-optical (MO) disks.' These conditions are dependent on the characteristics of the disk drive. This paper focuses on digital MO disks with a diameter of 130 mm which conform to the ISO standard. E-polarized incident light where the electric vector is parallel to the grooves is suitable for obtaining a stable servo signal and Hpolarized light where the magnetic vector is parallel to the grooves is suitable for a sufficient cross-track signal. Furthermore, a quadrilayer structure is desirable for the improvement of recording sensitivity and enhancement of the Kerr rotation.
