Crossfield tape head system: With the crossfield tape head system, the so-called premagnetization of the tape does not take place - as usual - via the recording / playback head, but via a separate sound head (bias head), which is opposite the aforementioned recording / playback head. This sound head arrangement enables signal modulation over the entire audio frequency spectrum without any impairment due to the premagnetization, as is the case with other sound head systems.
