  A few weeks ago I posted a question if it was possible
for an Atari ST to read MacIntosh discs or a Mac to read
ST discs.
  The answer I got was:

Atari reads Mac *NO*:

  An Atari ST can't read MacIntosh discs because the
mac varies the rotating speed depending on which track
the reading head is on.
There might be an solution in sight though:

>The company which produces the Magic Sac for David Small (Data Pacific
>I believe) is coming out with an interface which will allow the exist-
>ing ST drives to read/write Mac disks. I think the interface is very
>near to distribution but do some checking. It's hardware but you won't
->have to worry about loading any kind of program to get the job done.

  If anyone want to read IBM 3.5" discs this might be of interest.

Mac reads Atari *YES*:

  But you need software to do this.

->From: enea!batcomputer!othello (Michael Culbert)

->	It is possible for the Mac to read/write Atari disks, as the hardware
->in the Mac is entirely software controlled.. I have seen a program that does
->just this.. I think that it was on Compuserve, but I am not sure.  The Atari
->uses a very simple disk controller and a MUCH cheaper drive that is NOT multi
->speed, thus it is NOT POSSIBLE at all for the Atari to read/write mac disks.

  Many thanks to you three and the others that answered my question.
