8 Track Player For Car

The Compact Cassette, in appearance and function essentially a miniaturized version of the RCA cartridge, was introduced by the Dutch firm Philips in Europe in 1963, and in the U.S. in late 1964, but it took several years to achieve significant market penetration. Initially, the audio quality was too low to recommend it as a promising medium for music-listening. It seemed to be just another convenient new format for dictation systems and small battery-powered portable units designed for recording speech but not music. By the late 1960s, however, audio quality had been improved enough to make music reproduction acceptable to listeners willing to tolerate a limited frequency range and substantial background hiss in exchange for convenience and economy, and by 1968 AC-powered stereo cassette decks were available. Sony introduced a battery-powered portable stereo cassette recorder in 1970. After the introduction of Dolby B noise reduction for cassettes in the early 1970s, and the advent of new tape coatings that greatly improved the high-frequency response, the Compact Cassette finally became a respectable and increasingly popular medium for listening to music, both on the road and at home.
