<p>PURPOSE:To simplify the operation recording a program search signal by detecting a mute block part with a digital 0 signal, and recording automatically a signal representing inter-music when the detecting state is consecutive for a prescribed time. CONSTITUTION:A digital signal of an A-D coverter 2 is supplied to a rocording system digital signal processing circuit 3, divided at each prescribed number of sampling data, applied with coding and a signal is added thereto and formed into a block and recorded on a magnetic tape 10. If an analog input digitally converted or a digital input with 0 level is detected consecutively for a prescribed time by a 0 signal detecting circuit 4, it is regarded as the inter-music signal. Then an inter-music signal generator 6 is activated in the timing generated by a timing circuit 5 and a signal representing inter-music is added to a C&D section. Since the block read is attained by a turning head at program search, the program search of a music is attained by a signal representing inter-music.</p> |
