A data compression apparatus includes a receiver that outputs sampling sequences corresponding to signals obtained by adding different delay times to different signals obtained by branching a target signal into a plurality of lines, and sampling the signals at a sampling rate less than the Nyquist rate, and an encoder that converts the sampling sequences into compressed data. The encoder includes a sub-FFT that converts the sampling sequences into frequency-domain signals, a signal processing unit that performs, at one time, phase compensation processing for sub-Nyquist zones of the sampling sequences, and processing to cancel phase rotation, a target frequency estimator that determines into which sub-Nyquist zone the target signal has been folded and estimates the frequency of the target signal, and an encoding unit that converts a value representing the sub-Nyquist zone and the corresponding amplitude value into the compressed data and output the compressed data.

This invention relates to a stamper for optical disc and a method for manufacturing an optical disc by using this stamper. A photoresist is applied to a substrate () and this photoresist is exposed, developed and then transferred to form a disc master which has a recess/protrusion pattern formed on its one side. The one side of the disc master () is etched to narrow the width of a protruding part constituting the recess/protrusion pattern, and the recess/protrusion pattern of the disc master () with the reduced width of the protruding part is transferred to form a stamper (). The recess/protrusion pattern provided on the stamper () is transferred to form a predetermined pattern on a substrate of an optical disc.
