Commonly known as a cassette tape or an audiocassette, the Compact Cassette is a magnetic tape that carries analog audio signals, almost like the LP Record. Most cassette tapes carry up to 30 minutes per side (for a total of 60 minutes, or 1 hour). In such cases, soundtracks that exceed the 1-hour limit are split into two (or more) parts. Like the VHS format, the Compact Cassette phased out in 2006. However, some stores still carry blank recordable cassette tapes, usually in the C60 format.
Audio cassettes were often the norm before the Audio CD format existed in 1983. At that time, any soundtrack albums longer than a full hour were always split into two or more parts, resulting in the album being released in multiple cassettes.
