  • Abstract
    A compact magneto-optical disk drive compatible with current optical disk systems is reported. A tracking detection system enabling use with add-on (non-erasable) optical disks was adopted. High-speed accessing was accomplished by constructing the head from both stationary and moving mechanisms. Noise analyses showed that for large analyzer angles ¿A, Ndisk ≫ Nlaser ≫ Nshot, but when the SN ratio was maximum at ¿A ~ 10°, the three noise levels were roughly equal.
