Sense: noun/1
A CD (compact disc) stores only audio or small data files, whereas a DVD holds much more data — enough for a full-length film. Blu-ray discs store even more data than DVDs and offer higher picture quality, but require a Blu-ray player. Videotape is an older analog format that used magnetic tape inside a cassette; it was common before DVDs but the picture quality is lower and the tape can wear out over time. For everyday use in the 2020s, DVD remains the most widely compatible disc format for renting or buying films.

Etymology
DVD is an abbreviation that originally stood for 'digital video disc' when the format was introduced in 1995. As the technology expanded to store many kinds of data, the official name was changed to 'digital versatile disc', though the DVD abbreviation stayed the same.
