Abstract
An apparatus is provided for recording and/or reproducing video information and code data simultaneously on a video disc recording medium. The video information is recorded on the recording medium as FM-modulated carrier signals. The recording of such FM-modulated carrier signals is intermittently interrupted to record the code data. The interrupted or unrecorded portions of the otherwise recorded FM-modulated carrier signals is utilized to represent the video disc code data.
