Abstract:
There are provided an optical disk from which high-density data is reproduced and a reproduction apparatus that reproduces data from such an optical disk having high-density data recorded thereon. A photo-detecting section has two split detectors A and B in the direction of tracks on the disk. A signal processing section generates a TPP (Tangential Push-pull) signal made of a differential signal derived from detection signals from the detectors A and B, and further generates a reproduced signal by extracting from the TPP signal a high-frequency component signal in a record signal recorded on the disk. The signal processing section reconstitutes a high-frequency component signal in the record signal recorded on the disk by frequency-shifting the TPP signal obtained as a readout signal from a superimposed signal having the carrier signal and the record signal superimposed with each other.

Claim (Index 3):
The information processing apparatus according to  claim 1 , wherein\n the operation is a process of multiplying the TPP signal with the carrier signal, and the signal processing section performs the process of multiplying the TPP signal with the carrier signal in order to frequency-shift the TPP signal to the high-frequency component range in the record signal recorded on the disk.
