Abstract:
An exposure recording method for effecting recording on an optical recording material using a chemically amplified photoresist which needs a heat treatment process to reform an exposed portion after the material has been subjected to a far UV exposure process using a light beam focused by an objective lens, said method characterized in that during recording a light beam is focused onto the photoresist by the objective lens and the light beam is moved with a relative linear velocity .upsilon. across a surface of the material at between 10.sup.2 and 10.sup.3 cm/sec and a power density of the light beam is set to 4.upsilon..times.10.sup.2 W/cm or more, the power density being above that necessary to produce a developable image thereby performing the exposure process and the heat treatment process simultaneously.
