Method of and apparatus for recording information from a master medium onto a slave medium employing digital techniques
First Claim
1. A method of recording information on a recording medium that is reproduced from a master medium comprising the steps of:
- (a) reproducing information from a master medium at one rate;
(b) storing the information as digital information;
(c) retrieving the stored digital information;
(d) converting the retrieved digital information into analog information; and
(e) recording the analog information at a rate faster than said one rate onto a recording medium.

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.

6. Apparatus for recording information on a recording medium that is reproduced from a master medium comprising:
-
(a) a digital storage device; (b) circuit means for reproducing information from the master medium at one rate and storing the reproduced information as digital information into said digital storage device at said one rate, said circuit means retrieving the stored digital information from said digital storage device at a rate faster than said one rate and converting the retrieved digital information into analog information; and (c) a recording device receiving said retrieved analog information from said circuit means for recording said retrieved analog information on a recording medium at a rate faster than said one rate. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 25)
