ELCASET, rise and fall of a Hi-Fi tape system





ELCASET was an analog cassette tape based audio format developed by SONY in cooperation with Matsushita (Panasonic) and TEAC in 1976. It was intended to offer a reel-to-reel system sound quality in a convenient cartridge format. The name comes from the expression "large cassette" or "L-cassette". Although the ELCASET used a 6 mm (0.25 in) wide tape running at 9.5 cm/s (3.75 ips), twice the width and twice the speed of a PHILIPS Compact Cassette it became a complete failure in the marketplace and by 1978 it completely faded-out from the market. This happened mainly because Compact Cassette had a more compact format and the dramatical improvement with the introduction of new tape formulations such as chromium dioxide and lower noise with the introduction of the Dolby B noise reduction circuit.
