response: Well, the way they work is they're an analog sound storage medium, right, and so it's a flat disc that has these spiral grooves that are inscribed and modulated onto the disc
history: I think I want to start collecting old phonograph records I see. Did you know they're also called vinyl records as well? This classification excludes most made after WWII. I like them and think they are a cool addition to my other collections but do not know much about them
knowledge: A phonograph record (also known as a gramophone record, especially in British English, or record) is an analog sound storage medium in the form of a flat disc with an inscribed, modulated spiral groove.
