Abstract
Provided are a recording medium, a recording medium playing device and method, which has an EFM demodulation unit for adaptively realigning an EFM demodulation point. The recording medium demodulates first data into second data in response to a channel clock signal recovered from the first data, compares a demodulation point indicating demodulation of the first data into the second data with an alignment point set in response to the first data, and jumps the demodulation point forward or backward by a difference between the demodulation point and the alignment point.
