Heh, I may have just answered my own question.
I clicked the link (above) to Accurite, and from what I garner I was
essentially correct - there are "generic" discs which might cover many
mechanisms, but track spacing & count aren't the only relevant parameter.
Am I getting that right? =)

I might need one of these as well.
And here's a question for the experts: Why would one actually need a "1541
specific" alignment disk - wouldn't there be a generic alignment disk,
which would be suitable to all drives which use the same track (and not
necessarily even sector) geometry?
Isn't the alignment disc essentially a series of concentric analog
sine-wave audio tracks, with each audio track recorded on the centerline of
a disc data track?
It would seem that so long as the drive uses the same track spacing, one
disc could serve many mechanisms. Please correct me on that, if needed.

Ok, which disk would I purchase then?
I'm pretty sure Dan is after an analog
alignment disk. There was a
vendor mentioned here a couple of weeks ago, but I don't recall their
name.
