Abstract:

A recorder test fixture was assembled from previously tested components. A single-color DRAW optical system was designed, built and tested. Life testing of tellurium and bismuth films has continued with no change observed after 6000 hours at 90 C. Improved air sandwich disc configurations with metal hubs and supports were studied. A comparison of the optical disc and the best commercially available magnetic storage devices is given.
