Every time you record you degauss.
Forgive a naive Newbie but, is this true? [/B][/QUOTE]
The buildup of magnetism on a head is a non-problem. Remember what happens when you put juice to a coil? Here's a few important facts to know:
The most common cause for failure is wear. Using old tape wears faster, the epoxy binder breaks down releasing oxides which accelerate wear. Other factors are incorrect tape tension and alignment. As a head wears, its dynamic characteristics change. (You can recontour a head at 10% the cost of a new one)
The second most common cause of head failure is mishandling. Mishandling during installation or changeover is evidenced by broken connector, dinged or scratched tape contact, shifted gaps, or other damage which causes the head to fail at start-up or shortly thereafter. 'Tape contact must be intimate' in order to achieve proper saturation of the tape, and is even more critical during reproducing.(keep it clean)
To better understand the importance of tape to gap contact in the operation of any head it might help to understand how a head works. Very simply, a head records when an electrical current runs through the coil, creating a flow of magnetic flux which wants to go "round and round" inside the core, but due to the non-magnetic gap material in the face, the flux must "jump over" the gap to complete its path. The flux "jumping over" the gap magnetizes the ferric-oxide which is in contact with the gap area at that time. Reproducing takes place when the magnetized tape passes across the gap. This creates a flow of magnetism within the core which induces an electrical current in the coil.
