摘要:
In a reproducing apparatus, a reading unit reads an information signal from a storage medium, and a converter converts the information signal reproduced by the reading unit into a first digital signal by sampling the information signal in accordance with a reference clock signal with a predetermined frequency higher than the frequency of the information signal. An oversampling unit generates a second digital signal by increasing the number of samples of the first digital signal output from the converter. A data detector selects two adjacent samples from the second digital signal on the basis of the frequency of the information signal reproduced by the reading unit and a phase change of the information signal. The data detector then generates read data using the selected samples of the digital signal.
