  • Method and apparatus for producing an audio magnetic tape recording at high speed from a preselected music library
    Patent number: 4851931
    Abstract: The present invention relates to a novel method and apparatus for taking an analog audio signal, converting the signal into a digital audio signal, and thereafter converting the digital audio signal into a standard bandwidth video signal and thereby substantially compressing it. In this format, it can be placed onto a master video tape from which it can be transferred to a video disk. The present invention further comprises a method and apparatus from which a selected number of recordings on the video disk can be retrieved by playing the video disc in still frame mode to create an analog video signal, converting the analog video signal into a string of digital values, converting the digital audio stream into an analog audio signal and thereafter recording the audio signal onto an audio tape at high speed.
