Print-through is a generally undesirable effect that arises in the use of magnetic tape for storing analog signals, in which a signal recorded on one section of tape is transferred onto other sections in close proximity. It is caused by the pattern of magnetic fields recorded on the source tape influencing the ferromagnetic particles in adjacent tape to align with the source.
