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.
