There is also a 35 mm width, but this variety is more similar to the motion picture stock of the same width. It is referred to by the recording and motion picture industries as "magfilm". It is used for recording analog sound for a motion picture, and for interlocked playback of sound with a picture reel when editing motion picture film on a flatbed editor. It has also seen use for studio audio recording and mastering, a few albums released by the Command label in the 1960s were mastered using 35 mm magfilm. It has the same sprocket holes and the thicker acetate (or polyester) base of 35 mm negative or reversal cinema stock, but instead has a magnetic oxide layer, coating the full width of the film base (as opposed to a photographic emulsion). This variety is referred to as "fullcoat magfilm". Another variant, "stripe magfilm", has only three separate oxide "tracks" on the base, with the rest of the base being clear, with the same 35 mm sprocket holes as well.
