Personics

Personics was the company that invented the music recording retail system with trade name "Personics System" that was introduced in record stores starting in 1987. The system allowed customers to enter a music store, use headphones to preview and select individual songs on a console, then specify a custom list of songs to be recorded to a Compact Cassette tape. The songs available were also listed in magazine format available at the stores. The record stores had a machine from Personics that contained 120 custom Compact discs (2 drives with 60 discs each) recorded in CD Digital Audio Redbook format with custom Dolby AC1 (DP85) tracks which were also pre-encoded with Dolby B Type Noise reduction prior to compression. These two drives each had jukebox disc changing systems and provided access to thousands of songs for fast (8x speed) in-shell cassette recording.
