Recordon (1948 – mid 1950s)

The Recordon was an office dictation system using 9-inch paper disc with a magnetic coating. It was introduced by the UK company Thermionic Products in 1948 with the Recordon TP503 machine, made under license by the Brush Development Company of the USA that produced the Mail-A-Voice system.

The Recordon Recording Disc had fold lines printed on it, and could be folded for mailing. The system was fairly low fidelity, but was adequate for dictation purposes and as the recording runs from the centre to the outside of the disc, quality improves. Discs could be erased for re-use.

A couple of further models of the Recordon were produced, but in the mid-1950s Thermionic switched to the Agavox system.
