FLOPPY DISKS
The disks used in the 820-11 can be purchased from Xerox or from any computer or
office equipment dealer.
Disks will vary in quality and type.
When a disk is
marked "certified" for double density, it means that the surface is of a high enough
quality to allow you to record twice as many characters on the disk.
Disks
certified double sided are a high enough quality to prevent errors in recording on
either side of the disk.

•
Either Single Sided
(77
Tracks) or certified Double Sided
(77
tracks per side).
•
Double Density certified.

•
