The Cassette recorder is a staple part of technological history, for both its cultural impact on the music scene and its revolutionization of Audio-Visual hardware. As someone who has always had a fascination with the 70s and 80s, I wanted to research an object that would give insight into the life and culture of that time period. I chose The Sony Stereo Cassette Deck because I knew how influential music was in popular culture during this era and wanted to learn more about the last effects it had on technology advancing in the future. I learned that The Sony Stereo Cassette Deck (Model TC-K5) was made in 1977 by the Japanese electronics corporation Sony ¹. The company is based out of Minato, Tokyo, and was one of the largest manufacturers of cassette recorders in the late 70’s/80’s ². When it launched, this cassette deck retailed for around $300 and stayed in the market for 7 years until it was discontinued in 1984 ³. In conducting my research around cassettes, I began to understand how the Stereo Cassette made it possible for even more technological advancements to be made for portable cassettes in the years to come. In addition to this information, I was exposed through my research to the significance of the cassette recorder to pop culture because of its ability to create mix-tapes. As the technology for cassettes evolved in the early 80s, it became evident that the portability, accessibility and price of the cassette played a huge role in its success. With these developments, people found new ways to connect with one another via mixtapes ⁴. You would sit by your record player, put on your favorite song, start recording on the cassette and repeat the process in order to create a playlist of self-expression. All of these aspects that made the cassette allowed it to be a staple feature in American homes during this period, as well as a prerequisite for further advancing audio-visual technology in the later 80s’.
