Cassette tape completes 50 years. Remember historical photos

Younger readers may not remember, but there was a time when the most practical way to listen to music was with magnetic tapes. The cassette tape, popularly abbreviated as K7 in Brazil, is 50 years old.

The technology that was launched was developed by Phillips engineers and the company guarantees that the official production date is September 13, 1963. The cassette was created to replace the roll tape and 8-track format, which were similar, but much less practical and more spacious.

The technology included an audio tape 3.15 mm wide, which ran at a speed of 4.76 centimeters per second.
