No.  The Mac uses a scheme, halfway between CLV and CAV, involving 
changing the disk drive rotation speed in three bands on the disk.
The Amiga cannot do this, so you're out of luck.  There are more
specific reasons why not, but this argument got out of hand some years
ago, and I don't want to go into it now.  But I point out that the
folks at Central Point Software weren't able to do it after a LOT of
work, and I tend to take that as evidence supporting my position.
