Abstract

The mechanism of thermal interference and crowding on amplitude variation of the optical readout in a high density magneto-optical disk is studied. A simple method of eliminating the amplitude variation and achieving uniform amplitude of optical readouts in successive recording pulses is demonstrated. A thermomagnetic switching model is used to explain the mechanism for the thermal interference. A correlation model is also applied to describe how successful the thermal compensation is achieved. Good agreement is reached between the experimental and the simulation results.
