    摘要： An apparatus for recording and reproducing an information signal on and from an optical disc includes a memory. The information signal is written into the memory. The information signal is read out from the memory. An optical head generates a laser beam in response to the readout information signal, and applies the laser beam to the optical disc to record the readout information signal on the optical disc. A test signal is recorded on a position of the optical disc near a recording position thereof via the optical head during the writing of the information signal into the memory. The test signal is reproduced from the optical disc. The reproduced test signal is evaluated to generate an evaluation result. An intensity of the laser beam is optimized in response to the evaluation result.

    摘要： A recording medium includes a plurality of signal recording layers. A head reproduces two information signals from respective places in the recording medium on a time sharing basis. The reproduced signals are stored in a buffer memory before being outputted therefrom at first and second transfer rates respectively. The reproduced signals are transmitted from the head to the buffer memory on a time sharing basis and at a third transfer rate higher than the first and second transfer rates. Information amounts of the respective reproduced signals continuously transmitted from the head to the buffer memory are decided on the basis of a given relation among parameters including intra-layer seek times and inter-layer seek times related to the head, and the first, second, and third transfer rates.

    摘要： A disc-shaped information recording medium includes a laminate of recording layers on and from which an information signal can be optically recorded and reproduced from one side of the medium. Data areas are provided in the recording layers, respectively. The information signal can be recorded on and reproduced from the data areas while a laser beam emitted from an optical pickup is applied to the data areas. Optical recording test areas are provided in the recording layers, respectively. A test signal can be recorded on and reproduced from the optical recording test areas to decide optimum power values of the laser beam for signal recording. The test areas are out of overlap as viewed in a direction of propagation of the laser beam.

    摘要： An optical disc includes a data area, a first test recording area, a second test recording area, and a recording information management area. The first test recording area extends inward of the data area, and has a portion which has undergone test recording. The second test recording area extends outward of the data area, and has a portion which has undergone test recording. The recording information management area includes an address information area storing an address of the portion of the first test recording area and an address of the portion of the second test recording area. The recording information management area may further include a recording condition information area storing information representing a condition of the test recording the portion of the first test recording area has undergone and information representing a condition of the test recording the portion of the second test recording area has undergone.
