Is tape head degaussing a myth after all?

[Deleted member 89059]

Recently obtained a WM-D6C, because CDs are not old enough, DAT is digital and vinyl isn't portable. Googling "head demagnetizer", I came upon this:

I have no electrical and magnetic understandings (other than don't play with magnets in front of a CRT), so basically is what that person saying true?

Thank you very much.

Actually the residual magnetism probably arises mostly just from the motion of tape in the path. There are plenty of magnetizable parts in the tape path.

Empirically, demagnetizing the tape path (not just the heads) will result in increased HF response and decreased background noise (hiss).

Basically he's full of it.
Why are you asking over here instead of over there...?

What I'd like is an electrical engineer (or someone similar) do either confirm or deny what he's saying about the DC and AC fields and such. But thanks.

Can't help you then.
