ABSTRACT:
In a recording apparatus for a mirror mother tape to be used in a contact-type magnetic printing process, a chrominance signal of an incoming color video signal is converted into a down converted chrominance signal having a reduced frequency fC, a beat cancelling signal having a frequency 2fC is generated from the down converted chrominance signal, the beat cancelling signal is added to a luminance signal of the incoming color video signal thereby generating an added signal, and the down converted chrominance signal is combined with the added signal to provide a composite signal which is recorded on a mirror mother tape.
