A videotape is a recording of images and sounds on to magnetic tape as opposed to film stock used in filmmaking or random access digital media. Videotapes are also used for storing scientific or medical data, such as the data produced by an electrocardiogram. Charles P. Ginsburg invented the videotape. He worked for Ampex, and was inspired by the reel-to-reel machines used for recording sound.
