This invention provides a system that allows a customer to select various randomly accessible musical pieces to be copied at a rapid speed onto a tape for his immediate purchase, and that automatically forwards the appropriate royalty payments to the credit of the artists involved. In a preferred embodiment, the available selections are stored and edited on a video tape by means of an audio to video digital converter, are transferred to video disk to form a library, and are retrieved for duplication onto cassette tape by means of a video to audio digital converter. A much higher than normal speed of duplication is maintained with minimal wow and flutter by means of a burst mode input and a rate buffer to output. A synchronized stereo signal is retrieved from each frame of video format, without the expected phase shift problems.; An enhanced dynamic range is also provided by an increased number of bits of information being used for each sampling of the original analog signal. Details of each use of the apparatus are coded onto the medium receiving the copied selections.
