    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. The way of use of the optimal waveform correction values is changed in response to the recording/reproducing apparatus manufacturer information which is read from the optical disc. This information is recorded by the recording/reproducing apparatus in a former recording test.

    摘要： The present invention measures first and second detection signals respectively obtained at two focuses during a focus search by means of an optical head (2). Then, a type of a disk-shaped optical record medium is determined by a microcomputer in a system controller (7), from a comparison between characteristics of the first and second measured detection signals. Moreover, the present invention can measure an amplitude and a frequency of the detection signal obtained at the focus during the focus search to thereby determine the type of the disk by using the measured result. After the parameters are set in accordance with the determined result, the focus servo control is turned on. The present invention comprises a selecting means for suitably switching and selecting between two types of tracking error signals, measures first and second detection signals respectively obtained at two focuses during a focus search, determine a type of a disk-shaped optical record medium by using the first and second measured detection signals and then controls the selecting means in accordance with the determined disk type. Moreover, the present invention measures an amplitude and a frequency of the detection signal obtained at one focus during the focus search, determines the disk type by using the measured result and then controls a timing at which a servo control is turned on in accordance with a conformity of a lens to the disk.

    摘要： A recording medium has first and second areas on which first and second information signals are recorded respectively. The first information signal has a size Ya. The second information signal has a size Yb. A head operates for reproducing the first and second information signals from the first and second areas of the recording medium and transmitting the reproduced first and second information signals on a time sharing basis and at a predetermined constant transfer rate Rp while moving between the first and second areas of the recording medium. A buffer memory operates for receiving the first and second information signals from the head at the predetermined constant transfer rate Rp, for temporarily storing the first and second information signals, and for outputting the first and second information signals at first and second transfer rates Ra and Rb respectively. The first and second transfer rates Ra and Rb are lower than the predetermined constant transfer rate Rp. The predetermined constant transfer rate Rp, the first transfer rate Ra, the second transfer rate Rb, the size Ya of the first information signal, the size Yb of the second information signal, a seek time Tab taken by the head to move from the first area to the second area of the recording medium, and a seek time Tba taken by the head to move from the second area to the first area of the recording medium are in a relation as follows: (Ya + Yb) ≧ Rp·(Ra + Rb)·(Tab + Tba)/(Rp - Ra - Rb)
