PURPOSE:To dub even a piece of music in the middle of a tape freely by reproducing data on a recorded recording medium and also specifying the dubbing of its reproduced data at this time simultaneously. CONSTITUTION:This device supplies a one-shot signal to a music number counter 34 through an AND gate 33 which is closed with an opening signal (b). This music number counter 34 is cleared with a clear signal (d) from a CPU11 when an introduction play key (IP)7 is operated. The one-shot signal which is inputted subsequently is counted to obtain data indicating which music on the magnetic tape 17a a playback head 14a meets on the basis of the reproduced music right after the operation of the introduction play key (IP)7 as the 1st piece of music. This data is supplied as music number data N to a comparing circuit 35 and memory 36 and also converted through an AND gate 37 into a music number data detection signal (e) indicating whether data is present or not, and the detection signal (e) is supplied to a CPU11 to attain the purpose. |
