Abstract
In a signal reproducing device, for securing the stability in the steady state while enhancing the response of automatic gain control, a variable gain amplifieradjusts the amplitude of a reproduction signal outputted from a head amplifier. A gain control sectionincreases/decreases the gain in the variable gain amplifierby a predetermined change amount according to the large-small relationship of the comparison result outputted from a comparator. The gain change amount control circuitcontrols the change amount of the gain in the gain control sectionaccording to the frequency of inversion of the large-small relationship of the comparison result outputted from the comparator
