ABSTRACT:
There is disclosed method and apparatus for recording and retrieving video information in two modes on a single laser recording disc. An annular portion of the disc carries still frame information recorded at a constant angular velocity. One still frame occupies a track or groove extending around exactly one full revolution of the disc recorded at constant angular velocity. Thus, any given still frame is presented on the video screen by repeatedly scanning one track for so long as that particular still frame is desired to be shown on the video screen. Another annular portion of the disc carries video information, i.e. the dynamic parts of a video program, recorded at constant linear velocity along the track or groove being scanned on the disc. A scanning head may be selectively shifted beween the two annular regions in order to incorporate predetermined still frames into the video program at desired spots during the program. The disc drive speed is adjusted to provide the correct angular or linear velocity depending upon the portion of disc being played back at any instant. If desired, a controller automatically can fill the video screen with pertinent or interesting presentations during the brief time intervals whenever the scanning head is being shifted fron one portion of the disc to another.
