The cassette recorder was introduced by the Philips Corporation in 1963 and marketed in 1965 as an improvement over reel-to-reel recorders designed for portable use. It enclosed both reels of the recording tape in a small case which eliminated the need to thread the tape through individual reels. The tape width was just 0.125 inches (3.2 mm) and tape speed was 1.875 inches (4.76 cm) per second, which meant that sound quality was appropriate only for voice or dictation use at the time.
