摘要： Optical pickup is provided which includes a first reproduction channel for reproducing a first-type optical disk and a second reproduction channel for reproducing a second-type optical disk. When reproduction is to be performed on a third-type optical disk that is different from the first-type and second-type optical disks but reproducible via each of the first and second reproduction channels, the third-type optical disk is first test-reproduced both via the first reproduction channel and via the second reproduction channel, to thereby detect a jitter value of the information reproduced via the first reproduction channel and a jitter value of the information reproduced via the second reproduction channel. Then, the recorded information of the third-type optical disk is reproduced using one of the first and second reproduction channels that attains the jitter value closer to a predetermined target jitter value.

摘要： Prior to actual reproduction of an optical disk, test reproduction is performed with respect to a plurality of testing radial locations of the optical disk. In the test reproduction, waveform-equalization-characteristic parameters of the waveform equalization section are adjusted to optimal settings so as to optimize jitter of a reproduced RF signal detected at each of the testing radial locations of the optical disk. In the actual reproduction of the optical disk, the waveform-equalization-characteristic parameters of the waveform equalization section are adjusted to optimal settings that are predicted, from the optimal settings determined by the test reproduction, in accordance with a radial position or address, on the optical disk, of each location to be reproduced.
