Abstract

The stability of the read-back signal from an magneto-optical (MO) disk system was investigated as a function of read power, bias field, temperature, and number of read passes. At 2 mW read power and with the bias field turned "on," signal amplitude and jitter degraded markedly at the upper end of the American National Standards Institute (ANSI) temperature range. Signal amplitude erasure depends on bias field and peak temperature of the active layer. Jitter, however, is also dependent on the thermal gradients in the active layer.
