The oxide coating on MAGNETIC TAPE, composed of microscopic magnetizable particles suspended on a plastic film base or backing, such as acetate, polyester or mylar. During recording, the particles are re-aligned in correspondence with the input signal, and later during playback, these particles (also called domains) induce a similar current which reproduces the original signal. Tape without emulsion is called leader tape.
