DEFINITION

Classification: 369/231

Mechanism responsive to control structure on storage medium sensed by transducer support (e.g., trip device):

(under subclass 176) Subject matter wherein the storage medium has control structure thereon which is sensed by the transducer assembly support to modify the operation of the dynamic mechanism subsystem.

(1) Note. This control structure is often a lead-out groove.

47+, for control by an information signal.

52, for storage medium control structure sensed by other than the transducer assembly support.

178+, for record changing devices which may be controlled by a transducer support sensed control structure.

226+, for tone arm restoring controlled by similar structure.
