Minifon wire reel (1959 – 1967)

The Minifon name was applied to a range of miniature wire recorders introduced initially by the German company Monske & Co GmbH in 1951, and then produced by Protona GmbH from 1952 until 1967, although they were also sold under the Telefunken, ITT and EMI brands.

The recorders ran on batteries, and could record over 2 hours on a single reel of wire (later models allowed for 5 hours of recording). As the reels turn, the recording/playback head moved up and down so the wire was spooled evenly on each reel.

They were popular for covert recordings, and an accessory microphone that was made to look like a wristwatch was available. Minifon recorders were sold in overseas markets such as the US and UK.

In 1959 the Minifon Ataché was introduced, using a tape cartridge for the first time, but the wire-based recorders continue to be produced until Protona ceased production of all Minifon models in 1967.
