摘要： In an optical disk system using a PRML identification system, a method for deriving an optimum recording wave in a short period of time is provided. Parameters of the recording wave are adjusted by using an evaluation value obtained by a signal evaluation method which is suitable for the PRML identification system as an index. In this case, as a parameter adjusting method, a plurality of adjusting methods are utilized (S1-S3, S5).

摘要： A two-layer recording type optical disk capable of realizing stable recording and reproduction without being affected by another recording layer and an optical disk apparatus for the two-layer recording type optical disk are provided. In layouts of various areas in the optical disk, a position where a border between a recorded part and an unrecorded part is formed on one recording layer is set so that the position is always separated from a position where a border between a recorded part and an unrecorded part is formed on another recording layer by a predetermined clearance amount. Moreover, to a recording layer farther from an incident surface, test recording or data recording is always performed through a recorded part on a closer recording layer.

摘要： In order to evaluate the quality of a signal recorded on an optical recording medium, a target signal is obtained based on a predetermined data string and a predetermined partial response characteristic, and for each clock cycle, an equalization error is calculated that is a difference between the target signal and a signal reproduced each clock cycle. Further, the product of the equalization errors calculated at different times is obtained, and based on the obtained product, the quality of a signal is evaluated.

摘要： Reproduced signals are equalized by the least square technique by using a predetermined number of data samples binarized by a Viterbi decoder. Even when data written on an optical disk is unknown, the data can be equalized in a stable manner and can be reproduced at a low error rate without instability factors such as divergence due to interference.
