[net.audio] confused about tape head demags

ili (11/08/82)

           Help! I have been reading the recent articles about
tape head demagnetization.  It has been pointed out that some
servo decks are not compatible with the electronic head de-
magnetizers in the cassette shells. I have a servo deck and
one of each type of demagnetizer. I don't think I've used the
electronic one over a long enough period of time to cause damage
(My deck doesn't seem damaged).  My question is 

 *HOW DOES ONE KNOW IF ONE IS IN THE 80% WITH A COMPATIBLE
  COMBINATION OF SERVO DECK AND ELECTRONIC DEMAGNETIZER ?*

All replies are welcome either via the net or directly by mail.
