Thread: Wire audio recordings
face BY : Richard Prosser email (remove spam text)

I think you're talking about bias.

In the early days DC bias was applied - I think this included wire
recording. These days AC bias is applied at something like 100kHz. This
reduces noise (or allows increased recorded level which results in the same
thing) and reduces distortion. In both cases the bias is simply added to the
signal - not modulated by it (although I guess in the DC case it amounts to
much the same thing).

I also have wondered what sort of heads were used for wire recorders .
(Weren't flight recorders a wire recording until reasonably recently?)
