DefinitionGENERAL STATEMENT OF THE CLASS SUBJECT MATTER This class is an integral part of Class 369, Dynamic Information Storage or Retrieval, following subclass 18 and is the specific class for apparatus and corresponding processes for the storage and retrieval of information based on relative movement between a magnetic record carrier and a transducer. This class also includes apparatus and corresponding processes for making copies or editing of records falling within the above definition. A magnetic record carrier within the meaning of this class is an element which consists of a magnetizable material or is comprised of a coating or impregnation of magnetizable material which is intended for the storage of more than a single bit of information. Storage elements which include discrete magnetic areas, inserts, spots, etc. each intended for the storage of single bits of information, whether or not relative motion is used in transducing that information, are not included in the above definition. See elsewhere for the use of such elements. (See References to Other Classes, below.) SUBCOMBINATIONS OF DYNAMIC MAGNETIC RECORDERS OR REPRODUCERS This class includes elements forming subcombinations specific to apparatus within the class definition such as record carriers, transducers, etc. Electrical circuits not specific to magnetic recording or reproducing which may constitute subcombinations of such apparatus are classified in the appropriate class for such circuits. Mechanisms forming subcombinations of apparatus within the class definition are classified in the appropriate mechanical class providing for such subject matter unless claimed in significant combination with specific recorder structure. |
