SECTION I - CLASS DEFINITION
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.
| | (1)
Note. The record carrier must have continuous physical
extent over the path of movement and be able to store a time-varying information
signal. Static or discrete systems are classified elsewhere (see
References to Other Classes, below). |
| | (2)
Note. The characteristic variation is one which
must be retrievable by a transducer. Such variation producing
only a directly perceptible indication (e.g., a
graph), is classified elsewhere (see
References to Other Classes, below). |
B. This class includes processes and apparatus for
the copying or editing of a storage medium within the above definition
limited to such copying or editing including a step of storage or
retrieval by relative motion.
C. This class includes the record carrier, per
se, having particular information storage structure.
