The term "videodisk" may refer to a variety of storage formats for video content, including Laserdisc, DVD, Blu-ray, and HD-DVD. Other synonyms for videodisk may include video disc, optical disc, and digital disc. Some older videodisk formats, like Laserdisc, were large, vinyl-like records that could only store roughly an hour of video content. DVDs and Blu-rays, on the other hand, can store up to several hours of high-definition video and include advanced features like interactive menus, closed captioning, and bonus content. With the rise of digital streaming services, the popularity of physical videodisks has declined in recent years, but they remain a valuable format for serious film collectors.
