Paper Abstract

We have studied the influence of the pit shape upon the amplitude characteristics of the optical channel in an MO disk system, and studied three channel codings to determine their suitability for high-density recording. It is confirmed that magnetic field modulation with pulsed laser irradiation has the highest amplitude characteristics and NRZI format is most adequate for the method at the density of 0.6 micrometers /bit to 1.0 micrometers /bit.
