Micropolis Corporation (styled as MICROPΩLIS) was a disk drive company located in Chatsworth, California and founded in 1976. Micropolis initially manufactured high capacity (for the time) hard-sectored 5.25-inch floppy drives and controllers, later manufacturing hard drives using SCSI and ESDI interfaces.

History

Micropolis's first advance was to take the existing 48 tpi (tracks per inch) standard created by Shugart Associates, and double both the track density and track recording density to get four times the total storage on a 5.25-inch floppy in the "MetaFloppy" series with quad density (Drives :1054, :1053, and :1043) around 1980.
