Those are contacts, not the head gaps. Where is your "black sludge"

You are not making a lot of sense.
Both VCR and DAT heads get dirty, black stuff comes off them when you
clean them, then they work properly again.


Seriously, the only "stuff" you should see is maybe some shedding from
cheap tape, usually more brown than icky black. Do you have a lot of
smokers around?



Look, if you had bothered to read this thread properly you would know I used
to repair DAT machines for a living.

I know what it is to clean a dirty head, and I know what the results of
doing so is. I have done this a lot.

Clearly you haven't, but instead have probably destroyed a couple of heads
by cleaning them with a Q-tip, and then come to the perverse conclusion that
cleaning DAT heads does not work.
