Abstract
PURPOSE:To ensure a high-speed and accurate retrieval for an optional position, by recording the digital modulated signal like a character train, etc. on the same magnetic tape track as the analog signal and then reproducing the digital modulated signal. CONSTITUTION:A digital signal is recorded in an area between the recorded parts of analog signals, and at the same time a recognition signal is recorded to retrieve the position where the digital signal is recorded. A means is provided to control the driving of a recording medium by the reproduction of the digital signal or the detection of the recognition signal. For instance, a low frequency signal is recorded between the pieces of music, etc. in the form of a recognition signal along with a digital signal recorded as a name of music respectively. Then the digital signal is transmitted to a CPU via a demodulating circuit 16 while a magnetic tape is travelling, and the digital signal is displayed based on a RAM. While the fast winding and rewinding is carried out during the retrieval of a music and with a contact maintained between a reproducing head and the tape. Thus the recognition signal is detected.
