ABSTRACT:
A data recording system and apparatus used for recording on a recording medium an audio signal, compressed in time base with a predetermined compression ratio, together with a data signal for reproduction of the audio signal. The data signal is composed of serial data of bits. A dummy bit is provided before the head bit of the serial data with the dummy bit being in inverted relation to the head bit. A detection system and apparatus for detection of the data transmitted by the data transmission system, and a recording medium on which signals are recorded according to the data transmission system are disclosed.
