The Story

Elcaset was an answer to a narrow question: could a cassette sound as good as open-reel tape? Sony, Panasonic and TEAC jointly developed it in 1976. The shell was about twice the size of a compact cassette and held 1/4 inch tape running at 3.75 inches per second, double the width and double the speed. Sony put the EL-7 on the European market in mid-1976 and brought the line to North America in late 1977. Technics, TEAC, JVC and Hitachi’s Lo-D sold decks too.

The compact cassette did not stand still. Chromium dioxide tape and Dolby B noise reduction closed much of the sound-quality gap on the small format, and Elcaset machines cost far more and offered no portability. By 1980 the format was abandoned. The unsold stock, reportedly about 2,000 decks, went to a Finnish buyer who sold them at clearance prices. Nobody makes Elcaset hardware or tape now, and the format’s brief afterlife is in collectors’ hands.

A format can be better on the bench and still lose, because the cheaper, smaller one was good enough and already everywhere.

Worth remembering

  • The tape was 1/4 inch wide and ran at 3.75 inches per second, double the width and speed of a compact cassette, to bring reel-to-reel sound into a cassette shell.
  • Sony's top model, the EL-7, sold for about $1,000 in North America.
  • Besides Sony, decks were made by Teac (AL-700), Technics (RS-7500U), JVC (LD-777) and Hitachi's Lo-D (D9000).
