1950

The Tefi tape system is one of the most unusual and rare audio formats of the 1950s.

The system was developed in the early 1950s by the German company Tefi-Apparatebau (Tefi GmbH).
It is based on an endless magnetic tape housed inside special tape cartridges.
Unlike reel-to-reel tape machines, the system uses compact enclosed tape magazines.
The tape runs at a relatively high speed, providing very good sound quality.
Playback requires special players such as the Tefifon.
Music programs are released on pre-recorded tapes.
A single cartridge can hold up to four hours of music.
The system is mainly designed for home listeners who want high-quality music playback.
Despite its innovative design, the format remains a niche product.
With the rise of the vinyl LP and later the compact cassette, the system disappears from the market.
Today, Tefifon devices and tapes are considered rare collector’s items in audio history.
