High speed recorded information duplicating equipment
First Claim
1. A system for duplicating selected prerecorded items of information, the items of information being prerecorded on a source medium, the system duplicating the items of information onto a destination medium as a custom album, the system comprisingmeans for generating first digital signals corresponding to selected items of information on the source medium;
- means for storing said first digital signals in a master storage library under item addresses which individually identify each of the selected items of information;
means for retrieving the first digital signals from the master storage library and for generating second digital signals corresponding to a plurality of the selected items of information;
buffer storage means for receiving and storing said second digital signals and for generating third digital signals;
destination control means for controlling said buffer storage means and for controlling the recording of the items of information on to the destination medium;
said destination control means further includingcontrol processor for identifying the information in said buffer storage means;
memory address generator operatively connected to the control processor for generating address signals to access information in the buffer storage means;
bus control means operatively connected to said buffer storage means by a first bus for controlling the generation of said third digital output signals of said buffer storage means;
request control logic means operatively connected to said bus control means for controlling said bus control means;
byte unstacker means operatively connected to said buffer storage means for receiving and unstacking the third digital output signals of the buffer storage means; and
first-in-first-out (FIFO) buffer means operatively connected to said byte unstacker means for receiving the unstacked third digital output signals and for generating fourth signals.

Abstract
A customized album recording system is under the control of a central microprocessor or mini-computer. A master library or storage medium is filled with a repertoire of recorded information items (such as musical selections) which may originate with any suitable source, such as phonograph records, tapes, sound tracks, compact discs, or the like. Each information item is stored in the library under its own address. On read out, an operator keys in the addresses identifying the selected items which are read out of the library medium and stored in a large capacity memory, usually to provide about forty-five minutes of total listening time. Then, all of the music is read out of that large capacity memory and recorded at a high speed onto a suitable album size medium, such as a tape cassette, for example. The source music and the customized album music are usually recorded in an analog form. The music which is processed within the system is in a digital form. Thus, the various transfers of music from the master storage to the recorded album, may be accomplished at a high speed of digital transmission. In an alternative embodiment, instead of reading out an entire album amount of recorded information items, the central computer successively reads out limited amounts of data on a demand and fetch basis. A computer provides both the analog-to-digital and the digital-to-analog conversions in order to improve fidelity.
