A video recording disk is adapted to be rotated at a uniform angular velocity and to have bit positions of substantially equal length along a track, and the longer outer tracks are given more storage positions than the shorter inner tracks. Variable numbers of frames are located on each track revolution, depending on the data capacity of the track. Frames are divided into data units that correspond to a few horizontal lines, and frames on the same track are interlaced so that the data units of each frame are distributed evenly around the track revolution. The associated record player has simplified data storage requirements, particularly for freeze frame display of the television picture and for playing disks that hold video information in a data compression format.
A video recording disk of the type having a succession of track revolutions, comprising,
A player for a recording disk having a predetermined number of video frames recorded on each of a plurality of consecutive track revolutions, the video frames being divided into data units for a few horizontal lines of a video picture, said units for each frame being spaced around a track revolution substantially evenly and carrying an identifying header and interlaced with data units of other frames of the same track revolution, said player comprising,
