Abstract

PURPOSE:To eliminate the need for a circuit exclusively dedicated to reproduction for a lead-in and a return signal by recording the 1st audio carrier wave right before a main information signal recording zone and by recording the 2nd audio carrier wave for returning a reproducing element to a stand-by position right after the recording zone. CONSTITUTION:The 1st audio carrier wave is recorded right before a main information signal recording zone and the 2nd audio carrier wave is recorded right after it. Although a muting detection output is outputted from neither output terminals 10 nor 11 during main track reproduction, only the 1st carrier wave is recorded where the reproduction of a program is completed and the 2nd carrier wave is not recorded, thereby sending the muting detection output from only the terminal 11. Similarly, the muting detection output is sent from only the terminal 10 at the beginning of disk reproduction and a reproducing stylus is moved quickly toward an arm rest position or the recording position of the program. This constitution enables an audio demodulation system to be used in common, eliminating the need for a circuit dedicated to reproduction for a lead-in and a return signal.
