Default Re: Head demagnetizer cassette

Years ago I had one of those mercury powered cassette demagnetizers, it was next to useless and as Ted and others said, cassette heads never seem to get magnetized - I think maybe because the combined rec/pb in most self demagnetizes anyway? There are times a head can become magnetized, e.g. if you test them for impedance with an ohm meter, but it is other wise very rare. My deck has a removable headlock fortunately and needed serious realignment, when I bought it. After that, I demagged it away from the machine, as a precaution. The major danger is getting the wand near VU meters in situ.
