ABSTRACT:
A method of and apparatus for recording information from a master medium onto a slave medium. Analog information on a master medium is reproduced and converted into digital information. The digital information is stored in a digital storage device. The digital information stored in the digital storage device is recovered from the digital storage device and converted from digital information into analog information. The analog information is applied to a recording device for recording the analog information onto a slave medium. Information is recorded in the digital storage device at the same rate as it is recorded on the master medium. Information is recovered from the digital storage device at a faster rate than it is recorded on the master medium and the information is recorded on a slave medium by the recording device at a faster rate than it is recorded on the master medium. Thus, less time is required for recording information on a slave medium than is required for recording information on the master medium to reduce the duplication time.
