Abstract

PURPOSE: To realize the simultaneous recording of two programs as well as the record and reproduction of both the normal TV signal and the still picture by recording the information signals such as the TV signals or the like simultaneously into the different tracks via the different signal processes.
CONSTITUTION: The beam given from laser beam source 1 passes through half- mirror 2 and enters modulator 4 via reflector 3 to be then supplied to prism 9 the intensity of which is modulated by the FM wave obtained by modulating the signal of signal source 12 through FM modulator 6. The beam reflected at mirror 2 enters prism 9 underwent the intensity modulation by the output of FM modulator 7 through modulator 7. The two output are reflected by reflector 10 to be recorded via lens 11 on photo resist of original disk Da with shift of 1 track to each other. Also, the plural fields are recorded in a turn of disk Da, and the reproduction is carried out by selecting one of the two output.
