1. Apparatus for storing and reading video information on an optical recording medium comprising:

  • means for receiving an analog video signal having a first frequency bandwidth, said receiving means including a first low pass filter having a first predetermined cutoff frequency;

    distributing means for sampling the analog video signal and distributing the sampled analog signal into a number of distributed channels, each of which has a frequency bandwidth less than said first frequency bandwidth, and each of which includes a low pass filter having a second cutoff frequency, said first predetermined cutoff frequency being a multiple of said second cutoff frequency, said multiple corresponding to said number of distributed channels;

    means for recording a signal from each of said distributed channels onto the optical recording medium and for reading said distributed signals from the optical recording medium, said means for recording and for reading including a scanning laser which receives signals from a multiplicity of said plurality of distributed channels;

    means for reproducing said analog video signal by reassembling said distributed signals read from the optical recording medium; and

    means for outputting said reproduced analog video signal.
