Filed: 1985-08-05
Abstract: PURPOSE:To improve a tracking performance by detecting a dropout from a reproducing signal of a pickup reproducing element and preventing a high frequency component from a filter circuit from being transmitted to a synthesizing means only during detecting the dropout. CONSTITUTION:A part of a reproducing signal taken out from a pickup circuit 3 is branched and supplied to a dropout detecting circuit 19.
