A compact cassette, commonly known as a music cassette or simply a cassette tape, is a magnetic tape format for recording and playing back audio. It was introduced in the late 1960s and gained popularity throughout the 1970s and 1980s before being largely replaced by CDs and digital formats. Despite its decline in popularity, the compact cassette remains a popular medium for DIY musicians and hobbyists due to its affordability and ease of use.
