Abstract
An optical floppy disk system is described in which the optical disk is enclosed in a flexible housing which is optically transparent. Both the optical disk and its protective housing can be made at very low cost from inexpensive materials. The disk is enclosed within the protective housing and the housing and disk rotate as a unit during operation. The protective housing does not adversely affect the optics of the system.
