    摘要: A digital watermark embedding apparatus for embedding embedding information, as digital watermark, into an input signal having dimensions equal to or greater than N (N is an integer equal to or greater than 2) and a digital watermark detection apparatus for detecting the digital watermark are disclosed. The digital watermark embedding apparatus generates an embedding sequence based on embedding information, generates a N−1-dimensional pattern based on the embedding sequence, generates N-dimensional embedding pattern by modulating a periodic signal according to a value on the N−1-dimensional pattern, and superimposing the embedding pattern in the input signal and outputs it. The digital watermark detection apparatus measures a component of a predetermined periodic signal in a direction of a dimension of the input signal to obtain a N−1-dimensional pattern, obtains a detection sequence from values of the N−1 dimensional pattern, and detects embedded digital watermark based on a size of correlation value between the detection sequence and an embedding sequence.

    摘要: A disk reproducing apparatus with improved quality is provided which has a clamper and a clamper plate. By providing the clamp plate with connection portions radially extending from a radially inner peripheral portion toward radially outer peripheral portion of the clamp plate, the axial displacement relative to a clamp holder can be increased as compared to that in the existing structure. Moreover, by disposing the clamper on the radially inner peripheral portion of the clamp plate so as to be elastically deformable, the spacing in clamping can be increased to a drive part.
