摘要： From an optical disc on which physical address information is recorded in the form of phase modulation of a groove wobble, a wobble signal is optically obtained which is affected by the groove wobble. The wobble signal is phase detected by a phase detector (32) and then fed into a low-pass filter (34). In a jitter calculator (51) the value of σ/T is calculated from the standard deviation σ of a jitter distribution obtained from the output of the low-pass filter and the period (T) of a symbol clock for the phase modulation to evaluate the recorded physical address information.

摘要： A disk (1) has a burst cutting area (BCA) (10) formed by a crystalline portion and an amorphous portion, and the disk (1) 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 (10) 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.
