摘要： A disk has a burst cutting area (BCA) formed by a crystalline portion and an amorphous portion, and the disk is an optical disk (L-H medium) in which the reflectance of the crystalline portion is lower than that of the amorphous portion. The width Wcry of the crystalline portion in the BCA is lower than half the data period Wdat. Therefore, the average level of a BCA reproduction signal is unchanged regardless of whether the optical disk is an H-L medium or an L-H medium, so that focus control and reproduction of a BCA code can be performed even if a parameter of a circuit is a default.

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.
