[Locking heads on an RA81, etc]
Yeah, but moving them with the head lock while the positioner trys
to keep 'em on track may not be a great idea.
They might even jiggle and bounce a bit.

Three things never anger: First, the one who runs your DEC,
The one who does Field Service and the one who signs your check.
The only thing that I can think of is that if the
disk is spinning the
heads will have moved from the landing zone and the physical act of moving
the lock lever to the lock position will move the heads which could them to
crash.
Moving the heads with the disk spinning is conventionally called a
'seek', and doesn't normally cause a headcrash. Moving the heads with the
disk stationary is much more likely to do damage.
