摘要： PROBLEM TO BE SOLVED: To provide a multilayer recording medium that prevents deterioration of a signal characteristic due to a mirror effect that may occur between recording layers. SOLUTION: In the multilayer recording medium having at least one recording layer, a thickness of at least one spacer layer between adjacent recording layers is different from a thickness of the other spacer layers such that a beam focused on a recording layer is prevented from being reflected by another recording layer and further being focused on another recording layer. In the multilayer recording medium, a mirror effect is greatly reduced. In addition, the thickness of only the spacer layer exerting the most significant influence on the mirror effect is changed to prevent the deterioration of signal quality due to the mirror effect, and therefore, the structure of the multilayer recording medium is simplified.

摘要： PROBLEM TO BE SOLVED: To provide an optical disk unit and a wobble signal reproducing method.
SOLUTION: A light beam reflected from the irradiated optical disk is divided into at least four light regions in the direction corresponding to the radial direction of the optical disk to dect the light regions, and a wobble signal is detected by performing subtraction on a 1st difference signal obtained by subtracting a detected signal for the inner light regions of the divided/detected light beam and a 2nd difference signal obtained by subtracting a detected signal for the outer light regions of the light beam. Thus, when the wobble signal of the optical disk manufactured by a wobble modulating method is reproduced, the degradation of the wobble signal due to the interference (crosstalk) from adjacent track wobbles is prevented even for the optical disk the track pitch of which is reduced for increasing the recording density.
