Paper Abstract

A compact magneto-optical disk having 500 times the capacity of a 5-1/4 inch floppy disk is used for coded data storage. Low error rates are attained by the utilization of advanced highly sensitive polarization detection optics and high quality recording media. These fields of technology are developed based on noise analysis of readout signals. The disk drive can write and erase data by sectors and also play the current "write-once" type optical disk. This disk/disk drive unit promises to enhance the storage capacity of current office automation and other information systems.
