A. This is the generic class for processes of and apparatus
for the storage or retrieval of arbitrarily variable information
(as defined in the glossary below) which is retained in a storage
medium by variation of a physical characteristic thereof. The information
is stored or retrieved by causing or sensing a variation of a physical characteristic
of the storage medium by a transducer having relative motion along
a continuous path.
