Abstract
A signal recording and/or reproducing system is provided in a recording and/or reproducing apparatus having a control head for performing recording and/or reproduction of a control signal with respect to a control track on a tape, and a control circuit supplied and controlled by a reproduced control signal. The signal recording and/or reproducing system comprises a switching circuit for only passing signal parts in a signal reproduced by the control head which are required in the control circuit for control, a circuit for obtaining a signal which has passed through the switching circuit as a reproduced control signal and supplying this reproduced control signal to the control head, a modifying circuit for modifying signal parts recorded on the control track other than the signal parts required in the control circuit for control, and a discriminating circuit for discriminating signal parts within a reproduced signal obtained by reproducing the control track by the control head which are modified by the modifying circuit, to produce a discrimination signal.
