Abstract
A playback apparatus plays back information from a recording medium having a data structure including sync signals added in units of data items each having a predetermined size. The information is recorded in runlength limited codes, and the signals correspond to consecutive unique run lengths. The apparatus includes an information reading unit that obtains a binary data string as read information by reading the medium, a sync detection unit that performs detection of sync signals from the data string, and a data demodulation unit that obtains played-back data from the medium by performing demodulation on the data string with timing based on the detected signals. On the basis of detection, from the data string, of one detection pattern among types of detection patterns set as patterns including at least one of the unique run lengths, the sync detection unit regards the pattern detection as the signal detection.
