Abstract

PURPOSE: To record image signals in the recording medium on a rotary disc by recording the image signals concentrically on tracks with an arbitrary track as a reference signal.
CONSTITUTION: The light changing according to recording states is changed of its optical path by a reflecting mirror 4 and is converted to the image signal in a signal read-out circuit 3. At this time, the accurate tracking of the read-out tracks is controlled by the position deviation signal obtainable at the read-out. When the image signal to be recorded is next inputted to a signal write circuit 2, the light having been converted depending upon the intensities of the image signal is radiated to and recorded in the recording medium on a rotary disc 1. The tracking of this time is accurately accomplished because the reflecting mirror 4 at the read-out is also used.
