    摘要: A recordable optical disc has a plurality of test areas for effecting test recording therein with a light beam applied thereto which has an optional light intensity, a plurality of count areas for recording count information indicative of whether test recording is effected or not in the test areas, respectively, the count areas being associated respectively with the test areas, and an information recording area for recording information with a light beam applied thereto. The count areas are searched for an unrecorded count area with no count information recorded therein in response to a predetermined command. If at least one unrecorded count area is located, count information is recorded in the located count area. Then, the test areas are searched for one test area which is associated with the located count area in which the count information is recorded. The light beam is applied to the test area to effect test recording therein to measure an optimum light intensity for recording information in the information recording area. Information is then recorded in the information recording area with the light beam applied thereto with the measured optimum light intensity.
