1. An apparatus for producing an audio cassette tape composed of a multiplicity of randomly selected prerecordings comprising:

  • a. an Input Processor Means;

    b. said Input Processor Means further comprising an Analog to Digital Converter Means;

    c. a First Laser Disc Means;

    d. a Second Laser Disc Means;

    e. said First Laser Disk Means reading information in the forward direction and said Second Laser Disc Means reading information in a reverse direction;

    f. said First Laser Disc Means and said Second Laser Disc Means connected to said Input Processor Means through a Laser Disc Interface Means;

    g. Money Machine Means connected through a Money Interface Means to said Input Processor Means;

    h. a Keyboard connected through Keyboard Interface Means to said Input Processor Means;

    i a Central Processing Unit;

    j. said Input Processor Means connected through an Input/Output Interface Means to said Central Processing Unit;

    k. said Central Processing Unit comprising Random Access Memory and Programmable Read Only Memory;

    l. said Central Processing Unit connected through said Input/Output Interface Means to an Output Processor Means;

    m. said Output Processor Means further comprising a Digital to Analog Converter Means;

    n. said Output Processor Means connected through an Audio-Video Interface Means to a Monitor;

    o. said Output Processor Means connected through a Printer Interface Means to a Printer;

    p. said Output Processor Means connected through a Selection Interface Means to a Selection Duplicating Means said Selection Duplication Means including a cassette recorder which records at approximately 15 times normal speed;

    q. an audio selection library contained within said First Laser Disc Means and said Second Laser Disc Means;

    r. said Central Processing Unit further comprising an internal micro processor programmed for, controlling on input to the Random Access Memory in the form of laser disc information from First Laser Disc Means and Second Laser Disc Means, controlling keyboard information from said Keyboard, controlling money regulation from said Money Machine Means, controlling printer output from said Printer, and controlling audio signal duplication by said Selection Duplicating Means; and

    s. said audio selection library initially stored on said First Laser Disc Means and said Second Laser Disc Means wherein a desired selection is converted from an analog to a digital signal by said Analog to Digital Converter Means of the Input Processor Means and thereafter stored in said Random Access Memory of said Central Processing Unit from which the Central Processing Unit removes the digital signal selected and transfers it through said Input/Output Interface Means to said Output Processor Means and then to said Digital to Analog Converter of the Output Processor Means which transforms the digitized audio signal to the analog format, and then the analog format signal is transferred through said selection Interface Means to said Selection Duplicating Means from which the signal of the desired selection is transferred to a cassette and recorded at approximately fifteen times normal speed;

    t. whereby said Input Processor Means, said Central Processing Unit, and said Output Processor Means are interconnected by appropriate computer software to create an audio selection duplicating system wherein a selection of desired audio recordings which are stored on said First Laser Disc Means and said Second Laser Disc Means is chosen and input through said Keyboard and the appropriate amount of money is deposited into said Money Machine Means and the selections are transmitted from said First Laser Disc Means and said Second Laser Disc Means through said Input Processor Means to said Central Processing Unit and then to said Output Processor Means, and then to said Monitor where the selections are displayed, to said Printer where appropriate labels are produced and to said Selection Duplicating Means where the selected audio recordings are recorded onto a cassette at approximately fifteen times normal speed and the recorded cassette is thereafter dispensed from the system.
