Abstract: A method of and apparatus for recording information from a master medium onto a slave medium. In one embodiment, digital information on a master medium is reproduced and stored at a first rate, typically at real time, in a first high speed digital storage device such as a magnetic disk drive. The digital information stored in the first storage device, when needed, is transferred at a second rate, much higher than the first, to a second digital storage device in which it is stored until it is scheduled for duplication, at which time the digital information is repeatedly played back at a third rate, much higher than the first rate and slower than the second rate, is converted from digital information into analog information and applied to a duplicating device for recording the analog information onto a slave medium.
