Step-by-step explanation:
In 1985, if you were looking for the most advanced format for your home music listening experience, you would have likely been using a CD player. Compact Discs (CDs) started to gain popularity during the 1980s due to their superior sound quality and convenience compared to the cassette tapes that were commonly used until then.
The technology for CDs was based on the digital encoding of music, and they were read by lasers inside CD players, which interpreted the variations in reflections from the disc's surface. While the cassette tape's presence was still strong, and devices like the Sony Walkman remained widely popular throughout the 1980s, it was the advent of the CD player that represented the cutting edge of audio technology at the time.
