Title: Recording information on photosensitive discs - using laser beam to produce a track and modulated laser beam to record
Inventor: BUETTNER ULRICH
IPC: B23K26/351
Filed: 1974-02-02
Abstract: Information is recorded on a disc coated with photosensitive lacquer using an unmodulated beam to irradiate the disc in a first series of spots (e.g. circular) to form a track which a pick up head can follow and a modulated laser beam to irradiate the disc in a second series of spots (e.g. elliptical) which is superimposed on the first series of spots, the information (on which modulation depends) being recorded by the second series of spots.
