Print-through

As crosstalk (English print-through ) is defined as the long-term magnetic aftereffect with a pre-recorded sound signals and wound onto a tape reel tape recorder, with adjacent coils. If this unwanted phenomenon is Remanenzänderungen a magnetic layer by the stray field of magnetized neighboring layers. This caused by the crosstalk interference is called copy echo, which is to be found, especially after prolonged storage at audio or video tapes.

In audiotapes an echo effect, which can be heard depending on the winding direction before or after the signal arises. In videotapes of the impression of blur, increase the image noise or streaks formed.

The crosstalk can also be usefully employed, copying of direct band contact layer to layer while heating from a mother tape onto a blank tape.

The word echo here is somewhat misleading: The image copied to the adjacent coils, ie time- forward and time as a normal echo and delayed playback.
