A Laser Scanning Phonograph Record Player
When a laser beam is focused on a 45/45 phonograph record groove, the reflected light pattern is a curvilinear projection of the groove cross section. The position of the light pattern varies in response to the groove engraving. This paper describes one method for detecting these positional variations, and subsequent playback of the recording.
