       | +3 as well as the existing CPC systems that had them (in fact the
       | +3 used a modified version of AMDOS which ran the drives on the

         | Minidisc. I have discs that are 30+ years old that have been
         | abused their entire life and still work fine with no noticeable
         | degradation. I specifically choose this format to archive audio
         | because the disc housing works great for environmental
         | protection and I'd eventually like to give my music collection
         | to my children/grand children. The discs can also store data.

         | plug it into my computer so I can throw anywhere from about
         | 140mb-1Gb(hi-MD) per disk.
         | 
         | Officially they're rated to about 50 years, but if you sealed

       | 51/4 floppy - 3.5" floppy - Zip/Jazz Disks - CD/DVD Discs - Hard
