Yes, that's what it _usually_ does (its native format).  But if you look
at the tech docs, you'll see that it can also do group code, a fact
used to great advantage by Mac Emulators (with some additional hardware
to do the disc speed.)  I never tried it out myself, but I would have
loved to do a Apple DOS 3.3 compatible file system in 68K Assembler :-)
