Not standard. The disks it uses are physically different from "standard" ones.
They are physically the same as early WORM disks like the IBM 3363, though the media is
different.
The drive NeXT used was made by Canon, and is the same as the Canon DiskFile. However, you
cannot use a Canon DiskFile to read NeXT cartridges because the low level format is unique
to the NeXT.
So if you want to read NeXT MOs, you need a NeXT.
I have something like six units here, and none of them work. Including the one in my old
cube I bought in '95 which worked when I bought it, continued working for many years,
was possibly the last functioning NeXT MO in existence, and then just stopped while it was
in storage. I have the idea it could be coaxed back into life somehow, but they are just
about perfectly impossible to work on. If anybody has had any success repairing these, I
am unaware of it. One guy says he's had success, but won't share information, so I
am choosing to believe he's a liar.
Good luck. You're going to need it. /@:
