Abstract
A recording and/or reproducing method and corresponding apparatus are provided, in which in phase monaural audio signals are separately mixed with a clock signal and a data signal, which are opposite in phase to each other, and the mixed signals are recorded in separate channels on a recording medium. Upon reproduction and recombination of the signals recorded in the two channels, the clock signal and the data signal cancel each other out so that the listener hears only the combined monaural audio signals but the clock signal and the data signal can be separated from the reproduced two channel recorded signals prior to their recombination and be used to generate visual display data concerning the recorded signals.
