<storage> Commodore Business Machines's 3.5 inch disk drive for the
Commodore 64 and Commodore 128. The drive stores 800 kilobytes using an MFM
format which is different from both messy-dos 720 kb, and the Amiga 880 kb
The 1581 supports a poor imitation of directories which are really just
partitions and largely unused. It also supports burst loading like the Commodore
1571, but is actually faster as it is better designed. It has 3160 blocks free
The 1581 is the highest density C64 serial bus drive made by Commodore. However
Creative Micro Designs (CMD) make the FD2000 (1.6MB) and (until recently) the
FD4000 (3.2MB) 3.5" disk drives. GEOS users like 1581s as they are very fast
when used with GEOS.
