DEFINITION

Classification: 369/44.18

Rotary headwheel or scanner (e.g., for use with arcuate, transverse or slant tracks, etc.):

(under subclass 44.17) Subject matter wherein an optical component rotales through a 360 degree motion to follow a track.

(1) Note. Slant tracts or tracks transverse to the storage medium motion are found on tape or card medium where the medium moves before or as the beam is directed across the medium.
