Videotape is a means of recording images and sound onto magnetic tape as opposed to movie film. In virtually all cases, a helical scan video head rotates against the moving tape to record the data in two dimensions, because video signals have a very high bandwidth, and static heads would require extremely high tape speeds. Video tape is used in both video tape recorders (VTRs or, more common, video cassette recorders (VCRs)) and video cameras.
