    An electrical current that is sent through the tape heads during recording in order to insure that a minimum level of magnetization is going on at all times. This increases the frequency response of the recording by making it easier for high frequency portions of a signal to reach tape. Yet it also increases tape hiss, because it produces a chaotic non pattern" on the surface of the tape, which reproduces as noise.
