Patent ID: 8094536

Claim:
A reproducing apparatus comprising: a reading unit configured to read an information signal from a storage medium; a conversion unit configured to convert the information signal 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; a sample increasing unit configured to produce a second digital signal by increasing the number of samples of the first digital signal output from the conversion unit; and a data detection unit configured to select two adjacent samples from the second digital signal based on a frequency of the information signal read by the reading unit and a phase change of the information signal and generate read data using the selected samples of the digital signal, wherein the data detection unit detects the position of the read data on the second digital signal based on the frequency of the information signal read by the reading unit and the phase change of the information signal, and selects the two adjacent samples one of which is located before the detected position and the other after the detected position.
