DEFINITION

Classification: 369/101

Invisible radiation (e.g., electron beam or X-ray):

(under subclass 100) Subject matter wherein the radiant energy is either (a) radiation outside the visible spectrum (4000-7000A5), or (b) a subatomic particle (e.g., electron)

beam.

(1) Note. A charged particle (e.g., electron) beam may be considered either invisible radiation or a particular electrical current depending upon the manner in which such a beam interacts with the storage medium.
