DEFINITION

Classification: 369/178

Access of multiple storage elements (e.g., record changer):

(under subclass 176) Subject matter having production of additional motion of the transducer or storage medium to change the storage medium used for storage or retrieval.

(1) Note. Movement of the transducer mounting (e.g., tone arm) is so interrelated with multiple storage access, that documents classified herein will not ordinarily be cross-referenced to powered transducer drive in subclasses 215+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

30+, for similar subject matter having designation or

selection of storage medium to be used for storage or retrieval.
