Abstract:
The present invention provides an optical disc recording method of irradiating an optical beam to an optical disc including a basal plate made of synthetic resin which has a concavo-convex pattern formed in advance on one surface thereof, and a reflective coat made of metal which is formed over the concavo-convex pattern on the basal plate, to physically change the concavo-convex pattern so as to record identification data.
