Sono Tape

French tape duplication plant located in the Paris suburb Plaisir, established in 1971 as the cassette and cartridges division of Imprimerie. The company used tapes by BASF for cassettes and by 3M for cartridges. The cassette cases were manufactured in the group's plant in Saussay and the cartridge cases imported from the USA. The facility was equipped with Dolby and had a reputation for being a quality duplicator.

On the subject of piracy, in 1979 Audio Graphic Industries (AGI) was taking steps to render the illegal duplication of cassettes more difficult and used the same type of leader tape with print SONO - TAPE [AGI logo] for all its products and the [AGI logo] was engraved in the plastic.

It is as yet unknown when activities ceased, but by the late 1980s Disco had taken on all duplication activities itself.
