ROTARY HEAD TYPE MAGNETIC VIDEO RECORDING AND REPRODUCING SYSTEM

摘要

ROTARY HEAD TYPE MAGNETIC VIDEO RECORDING AND REPRODUCING SYSTEM A recorded signal reproducing system includes a signal generator circuit which produces a tracking control signal in response to an output from a detection circuit which detects that a difference between an output of a peak hold circuit which holds a maximum amplitude of an envelope of a reproduced signal from a rotary head for a relatively long period and an output of an envelope detection circuit exceeds a predetermined threshold. The tracking control signal is used to control a relative positional relationship between the rotary head and a magnetic tape for controlling tracking during the playback operations.
