    • An apparatus for controlling an emission power of a laser diode is used in an apparatus for recording and reproducing information of an optical disk, which has a power calibration area and to which a disk discrimination code is recorded. The controlling apparatus is provided with: a power detection device for detecting an optimum recording power of the laser diode with respect to the optical disk to be recorded by use of the information reproduced from the power calibration area; a temperature detection device for detecting a temperature of the laser diode; a memory device for storing the optimum recording power detected by the power detection device, the temperature detected by the temperature detection device and the reproduced disk discrimination code; and a control device, to which the disk discrimination code reproduced at the present time is inputted, for comparing the temperature at the present time detected by the temperature detection device and the temperature stored in the memory device corresponding to the inputted disk discrimination code, and instructing the power detection device to detect the optimum recording power if the difference between the compared temperatures exceeds a predetermined value before a recording operation of the recording and reproducing apparatus.

    • 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.
    • 可记录光盘具有多个测试区域,用于在其中施加具有可选光强度的光束进行测试记录,多个计数区域用于记录指示在测试区域中是否进行测试记录的计数信息 分别与测试区域相关联的计数区域和用于记录施加有光束的信息的信息记录区域。 根据预定命令,对计数区域进行无记录计数信息的未记录计数区域的搜索。 如果至少存在一个未记录的计数区域,计数信息被记录在定位的计数区域中。 然后,搜索测试区域与记录计数信息的位置计数区域相关联的一个测试区域。 将光束施加到测试区域以在其中进行测试记录,以测量用于在信息记录区域中记录信息的最佳光强度。 然后,利用所测量的最佳光强度将信息记录在信息记录区域中,其中施加有光束。

    • 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.
