RE: # of tracks on amiga floppies.

["Eric K. Miller" <emiller%thecreation.com@localhost>]

I remember in the good ol' days that some companies pushed the heads out to 
track 81 and put copy protection information there so when you went to copy the 
disk, the standard copy wouldn't copy the 81st track.
 
This worked on the original A1000 and A2000 drives, but that's about the extend 
of my knowledge. :)

You should mention your drive model when asking this... I expect this to be
a function of the drive model. Of the drive mechanics, actually.

(Not that I'd know the answer for any of the models --- afaik, all official
documentation, at least by Commodore Inc., only mentioned 80 tracks and I
don't think there are any official thinks outside track 0..79...)
