PURPOSE:To make a reproducing signal continue easily and satisfactorily by installing a starting indentifying signal at the tip of respective segmetns. CONSTITUTION:A video signal is recorded through a recording circuit 2, a switch 4, an FM modulating circuit 5 and a head 6 to a disk D. On the other hand, a sound signal is A/D converted 13 and stored in a memory 14, and thereafter, the signal is read and D/A converted 15. The writing to the memory 14 is executed by the output of an oscillator 21, the reading is executed by the output of the high frequency of an oscillator 21, and the sound signal is compressed by the time base. A start identifying signal and an end identifying signal are inserted before and after the compressed sound signal at a mixing circuit 16 and supplied to a modulating circuit 5. At the time of reproduction, the video signal of the signal FM-demodulated 32 is stored in reproducing circuit 34, and the sound signal is A//D-converted 42 and stored in a memory 43, and thereafter, they are D/A-converted and supplied to a decoder 45. At such a time, respective start/end identifying signals are detected 56, and the sound signal is extended and continued at the time of the reading from the memory 43.
