fast home remedy to de-magnitaze recording head
 

any engineers with hints for me...or do i need to buy something to do it?
thanks

The Annis Han-D-Mag is around $60 now, and does a pretty reasonable job of
it.

I'd first, though, find out how it got magnetized in the first place. Has
the machine been near anything with a strong magnetic field? Is a head
blocking capacitor bad and throwing DC across the head?

A local studio might be willing to rent you a demagnetizer and a magnetometer
so you can track the source of the problem down.

I covered this in alt.radio.broadcasting....but I'll go into detail here.

You want a device which is designed to provide the appropriate amount of
magnetic flux to the head without overdriving the amplifier that it's
connected to. Too much and you'll smoke a very low power device, too little
and you won't do the job on the head. Thus, you need to get a head
demagnetiser. They're not expensive. True, you won't be using as much as
you would the tape machine you're maintaining, but it's a good investment,
since your recordings (I would assume) are worth far more than the $20-30 a
demagnetiser will set you back. If you're really strapped, perhaps you
could borrow one from someone who has more resources, or maybe you could all
buy one you could share, since you won't need it but for 10 seconds every
100 hours...surely under those circumstances there's no need to actually own
one solely on your own.
