<p>PURPOSE:To accurately and surely attain the program searching of a tape end music by making effective a detecting signal output with music searching by means of a first detecting means only near the numeric value of a counter stored into a second detecting means. CONSTITUTION:When the program of the end music is searched at the time of syncro-copying, and the tape arrives at the end, music searching is executed by a rewinding action in a music searching circuit 1, the interval of the music is detected based on the level of regenerative signals supplied from a head during the searching, and the detecting signal output is generated in the music top part of the tape end music. When the tape is rewound until a stored counter value, the detecting signal output is generated from a memory counter circuit 2. Further, an AND is obtained by a gate circuit 3, the output from the music searching circuit 1 becomes effective only in the range of the numeric value at which a counter is stored, and it is outputted as the music interval detecting signal. Thus, the program searching of the end music is accurately and surely attained.</p> |
