  Actually, DDS and DDS2 different media, but not as in
different form factors. IIRC, DDS1 is 90m, DDS2 is 120m, and DDS3 is
also 120m. They have and identifier embedded in the media that tells
the drive which DDS the tape is. I know for sure that a DDS1 drive will
simply spit out a DDS2 or DDS3 tape, and I think that holds true up the
line.
  A DDS2 drive will read DDS1 archives, and write a DDS1 tape in DDS1
format. I dunno about DDS3. Every shop I've worked with who used DDS3
drives used DDS3 tapes exclusively.
