    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.

    摘要: Recorded information is reproduced from a recordable optical disc with a light beam applied from an optical pickup to the recordable optical disc. The recordable optical disc has a program area for recording main information, a PMA area for recording recording history information relative to main information which is in the process of being recorded in the program area, and a lead-in area for recording, as index information, recording history information relative to main information which has fully been recorded in the program area. While the recordable optical disc is at rest, it is determined whether index information is recorded in the lead-in area, and if index information is not recorded in the lead-in area, the optical pickup is moved to a region of the PMA area where the recording history information is recorded, while the recordable optical disc is at rest After the optical pickup has reached the region, the optical pickup reads the recording history information while the recordable optical disc is being rotated. After the recording history information has been read from the region, the optical pickup is moved to the program area while the recording optical disc is being rotated at a constant speed.
