CROSS-FIELD HEAD RECORDING SYSTEM
On conventional recorders, the signal and bias are applied
to the same recording head. Therefore, the frequencies
recorded, especially high frequency signals, tend to be
attenuated or erased by the effect of the bias field.
With the exclusive AKA! CROSS-FIELD HEAD, however,
the signal and bias heads are mounted separately in
opposition with each other with their centers slightly off.
As the recorded signal is entirely unaffected by the
prevailing effect of the bias field, tape can be recorded over
the entire frequency spectrum with maximum fidelity even
at low tape speed.
