ABSTRACT:
An information recording and/or reproducing apparatus including a record parity signal adder for receiving error corrected compressed information and an error corrected control signal both of which have been corrected based upon a transmission parity signal added to the compressed information and to the control signal. The record parity signal adder adds a record parity signal to the compressed information which is different from the transmission parity signal. A modulator is provided for modulating the record parity signal added compressed information and a recorder is provided for recording the compressed information modulated by said modulation means. A controller is provided for controlling a start of recording of the recorder based upon the error corrected control signal.
