I have an official 1541 alignment disk.
I forget which one it is, but it's an original disk.
It has software on the disk you run as well,
I think it was freedom-1541 or something.
I think I asked years ago about duplicating these,
but is there a practical way to do that with just a 1541?
I mean, if you align a drive using a scope with the disk,
then duplicate it, how reliable is that copy for alignment of other drives?

  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? =) 
 Yes, your 'scope test point is essentially the output of the read
 amplifier; hence, the term "analog" alignment diskette.
