DRIVE SERIES SPECIFICATIONS
1040/1050 S-100 Series Floppy Disk Sub-Systems
The Micropolis 1040/1050 S-100 Series Floppy Disk Sub-Systems consists of ready to be used systems, which
means an enclosure plus installed drives.
These subsystem modules use drive mechanics from the Micropolis 1015-Series of OEM drives.
The drives designated as Mod. II are sometimes marketed as the MetaFloppy™. Lower capacity
Mod. I drives are sometimes marketed as MacroFloppy™
The MacroFloppy / MetaFloppy series marks Micropolis' second generation of floppy drives and subsystems, coming after
the pioneering first iteration that was the 1015/1016 "MegaFloppy" series. This newer
generation used improved controller cards, like the 100164,
which were able to encode data via GCR which raises recording density on the magnetic medium. In combination
with the earlier generation's doubling of magnetic tracks from 48TPI to 100TPI, this roughly quadrupled capacity
(Quad Density) over traditional Double Density (DD) 5.25-inch floppy disk storage.
Floppy drive subsystems utilizing a 35 track drive are called "MacroFloppy" and "MetaFloppy" subsystems rely on drives
writing 77 tracks.
Regarding the internal floppy drive mechanic, 48tpi/35 track drives have a black disk load actuator and 100tpi/77 tracks
drives have a blue disk load actuator.
