Abstract:

The device enables analog or digital data, stored on a conventional phonograph disc, to be read by a non-contacting optical read-head, which functions as an optical phonograph needle. A built-in servo system enables automatic closed-loop tracking of the groove being read. The device has economic and performance advantage over other existing data storage devices in applications where many copies of the same data base needs to be available for readout at different locations. Since the read head is non-contacting, no record or stylus wear occurs, and the potential bandwidth or speed of readout is many times greater than for a conventional phonograph stylus, being limited only by the receptor photocell and associated electronic circuitry.
