摘要：
A video signal reproducing system having a normal signal reproducing mode and a still signal reproducing mode includes a control signal generating means for reproducing a still mode control signal. A support means for supporting a signal reproducing means is responsive to the still mode control signal, whereby the signal reproducing means is maintained in substantial alignment with a recorded track of a recorded medium. Accordingly, the mis-tracking of the signal reproducing means relative to a predetermined recorded track is prevented, when the still signal reproducing mode is selected.
