Tape Recorder (and Walkman)

Invented by: Valdemar Pousen
Nationality: Danish     Date: 1898
 Purpose: initially, a telephone message-taking device; nowadays, largely music recording
 
     Poulsen's first magnetic recording device used wire and then later, steel tape. It was designed to record telephone messages.
     In 1935 the first plastic recording tape was introduced; it was coated with iron oxide (tape today is often coated with chromium oxide). Early tape recorders were buky machines with the tape running from one large reel to another.
     In the 1960's Philips introduced the compact tape-cassette. This was a complete, easy to handle, plastic package of twin spools and narrow recording tape.
The cassette led to Sony's invention, in 1979, of the Walkman.
     It was a complete, portable, stereo cassette player, little larger than a cassette box. There was no room for a loudspeaker, so earphones were provided, with tiny, superefficient plastic membranes.
     Now they're everywhere. And the sound reproduction is excellent-except for outsiders!
