Abstract

PURPOSE:To execute the high performance of an automatic tracking adjustment by comparing the output difference between the synthesizing envelope detecting output signal of a video signal and a HIFI signal and the synthesizing peak holding output signal of the video signal and the HIFI signal with a prescribed threshold and executing the tracking adjustment. CONSTITUTION:A video envelope detecting output 23 is potential-divided by a potential divider 125, on the other hand, an HIFI envelope detecting output 123 is potential-divided by a potential divider 127, this is added to an adder 130 and a synthesizing envelope signal is obtained. A video signal peak holding output 24 is voltage-divided by a voltage divider 126, on the other hand, a HIFI peak holding output 124 is voltage-divided by a potential divider 128, this is added by an adder 129 and a synthesizing peak holding signal is obtained. It is discriminated whether or not a voltage difference between a synthesizing peak holding output voltage which is the output of the adder 129 and a synthesizing envelope detecting output which is the output of the adder 130 exceeds a prescribed threshold, and the tracking at the time of reproduction is controlled. Thus, the high performance of an automatic tracking adjustment can be executed.
