Some might think all this attention to filtering is
overkill but after seeing
the illustration on p. 1-17 of the 1976 RK05 maintenance manual of the 100um
head flying height versus various contaminants, I have been very careful
about dust.
Ah, yes... THAT illustration - should be the same as on the disk pack
plastic
bags...
Large and loose particles are mostly kicked off by the heads. With a little
noise. Everything that sticks (i.e. the foam) makes a mess...
It's a relief that Philipp has had not-so-bad
experiences with
head crashes but I would like to minimize the risks.
I did not want to express that
I like crashing disks....!
My experience is: Crashed disk, much cleaning. Most times even the pack still ok.
On the other hand I currently have an RK05 with some head problem: I cleaned the
heads as well as possible. But one of the heads doesn't fly well anymore. It
collects oxide from the disk. You don't see any defects. But the head has to be
replaced.
Another myth (spelled correctly?) from the manual is: If the heads *EVER* touch
each other, they're gone. I'm very careful with the heads. But sometimes you
have a drive where the heads have "fallen out" either onto the pack or onto each
other. In those cases I have not seen problems after cleaning. One probably
should avoid letting the heads hit each other too hard.
