<p>A method for manufacturing an optical recording substrate in which an uneven and/or grooved surface of a stamper is brought into contact under a reduced pressure with an organic polymer sheet having the glass transition temperature between 120ºC and 190ºC, the double refraction retardation of the single path between +10 nm and -10 nm, and the thickness of 0.35 mm or under, and heated and pressed thereon. According to this method, it is possible to produce an optical recording substrate capable of easily transferring stamper pattern to the thin organic polymer sheet without fail.</p> |
