Optical type recorder and reproducer

Abstract

Abstract PURPOSE:To switch the mode to a recording mode when the end of recording is again detected, through jumping a light beam to an adjacent track, after detecting the end of recording at a reproduction mode, in making new recording to the next track of the recorded part of a guide track. CONSTITUTION:In recording a new signal succeedingly to the recorded part of a guide track, a recording signal is detected with a photo detecting element 27 at reproduction and when the recording signal is absent, a jumping instruction is outputted from a logical circuit 40 via a recording signal presence and absence detecting circuit. The output of a jumping instruction circuit 41 is applied to a jumping signal generating circuit 32 and to a mode switching circuit 29 to jump the scanning position of a light beam 21 to an adjacent guide track, allowing tracking scanning of the recorded part again. When the light beam 21 passes through the final point of recording, the logical circuit 40 generates a pulse output triggering a REC period set circuit 42 with the output of an recording signal presence and absence detecting circuit 39 to form the recording mode.
