Commodore 1581
1581
<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
formats.
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
when formatted.
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.
