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.
Because the information stored in the first digital storage device is not directly used in production, the duplicating device can be duplicating information previously transferred from the first storage device to the second at the same time information is being reproduced from a master medium and loaded, in real time, into the first storage device.
