Abstract: PROBLEM TO BE SOLVED: To prevent an error (residual error) on a focus servo system side of the recording/reproducing laser beam from being applied to a focus servo system of a servo laser beam as disturbance, by focus servo control during reproduction. SOLUTION: A first focus error signal obtained by receiving a first light beam is subtracted from a second focus error signal obtained by receiving reflected light of the second light. Based on the second focus error signal obtained by subtracting the first focus error signal, second focus servo control is performed by driving the second focus mechanism. Residual error components in a first focus servo control system is prevented from being superimposed on a second focus servo control system. COPYRIGHT: (C)2011,JPO&INPIT

Abstract: PROBLEM TO BE SOLVED: To expand the capacity of an optical recording medium which forms a void hole mark in a bulk layer. SOLUTION: A void hole mark column is recorded by changing a mark spacing of one kind of mark length, while a recording layer which records a void hole mark column in spiral shape is formed in multilayer in a depth direction. This is considered as so-called mark position recording. As for the recording layer which is formed in multilayer, all or part of spacings between the recording layers and the recording layers are made to be ≥5.2n λ/NA and ≤12.4n λ/NA.
