The Micropolis 1200 series of hard disk drives is a lineup of three models of full height 8-inch storage devices.
Introduced in 1983, they represent a first step in Micropolis' early storage solutions. The actual platter containment is of lower
height, making space for a controller board sandwiched on top while fitting the 8 inch Shugart mounting slot. Note that the drives
in this series all have a proprietary ANSI inferface.
As Micropolis Corporation's first step into hard-disk technology, these drives share many traits with their floppy disk
predecessors. These early drives have no fixed formatting. Instead, the magnetic surface can be utilized to write any format of
data inside tracks and even track density is variable. The controller board in use determines the format written.
Common choices are MFM and GCR encoding schemes. Please refer to the serie's specifications below for differences in
capacity and performance with MFM and GCR encoding. The device's mechanical drive mechanism is accurate enough to satisfy
positioning needs of MFM, GCR and RLL encoded information on the platter.
