PROBLEM TO BE SOLVED: To provide a device and method for disk reproduction in which an operation frequency of a demodulation circuit is reduced. SOLUTION: The disk reproducer for reading data recorded on a disk and generating reproduction data is equipped with a synchronism detection circuit 21 for detecting a specified synchronizing pattern included in data and identifying a detection timing and an EFM demodulation circuit 23 for extracting a part of the data out of data read from the disk selectively in sequence, putting together a plurality of extracted data, and converting them into corresponding demodulation data.
