APPARATUS FOR REPRODUCING INFORMATION FROM A MAGNETO-OPTICAL STORAGE MEDIUM

摘要

An improved apparatus for reproducing information from a magneto-optical disk is disclosed in which the differential ratio for reproducing signals can be automatically adjusted. The apparatus has a differential amplifier for performing the differential amplification of signals reproduced from the a disk; an automatic gain control circuit for receiving the differentially amplified signal and producing an automatic gain control voltage; and a differential ratio determining circuit for determining a differential ratio, based on the automatic gain control voltage output from the automatic gain control circuit. The differential amplifier performs the differential amplification at the determined differential ratio,
