A laserdisc is a type of disc used for storing and playing video and audio content. It was introduced in the late 1970s and was known for offering high-quality video and audio compared to other formats of its time. The disc is similar in appearance to a large vinyl record and requires a special player to read and play it. Laserdiscs were popular for their superior picture and sound quality but were eventually replaced by more modern formats such as DVDs and Blu-rays.
