52CONTROL STRUCTURE ON STORAGE MEDIUM SENSED BY OTHER THAN TRANSDUCER SUPPORT (E.G., CONDUCTIVE STRIP, NOTCHED EDGE SENSOR)

DEFINITION

Classification: 369/52

CONTROL STRUCTURE ON STORAGE MEDIUM SENSED BY OTHER THAN TRANSDUCER SUPPORT (E.G., CONDUCTIVE STRIP, NOTCHED EDGE SENSOR):

(under the class definition) Subject matter wherein the storage medium has an element thereon which is sensed by an electrical detector distinct from the intelligence transducer support wherein the detector controls an operating condition of the storage or retrieval apparatus.

(1) Note. The additional structure on the storage medium is not a recorded signal, which is classified elsewhere.

SEE OR SEARCH THIS CLASS, SUBCLASS:

14+, for control by a recorded signal of a type diverse from the information signal.

47+, for control by reproduced signal.

231+, for mechanism control structure sensed by transducer support mechanism.
