Any unwanted electrical disturbances, other than crosstalk or distortion components, that occur at the output of the reproduce amplifier.

System Noise: The total noise produced by the whole recording system, including the tape. Equipment Noise: The noise produced by all the components of the system, with the exception of the tape. Tape Noise: The noise that can be specifically ascribed to the tape. There are several sources of tape noise. See DC Noise, Erase Noise, Modulation Noise, Saturation Noise, and Zero Modulation Noise.
