Last night I cleaned the hell out of both the

even tried Brakekleen on the leading surface of the bottom head but it
didn't remove anything. I had the best results with putting lint free
cloth soaked in 99.9% isopropyl alcohol between the loaded heads. Got the
top head clean except for a wide line somewhat less than 0.1" wide that
goes from top to bottom. It's so perfect it looks like the head was
somehow made that way. Bottom head only had a few small blemishes left.
Well, good for you! I went rummaging around a bit in my hellbox looking for several
rolls of 3M diamond lapping tape that I picked up years ago, but no luck. The stuff is
great--you can use the half-micron stuff on a scratched-up head and it would come out
looking like new.
Wow, that stuff is expensive.
I mean... diamonds. But still. I suppose if I needed it, it would be
worth $300 a roll, but I don't need it that badly.
