ABSTRACT:
The invention provides a recording medium as well as a recording apparatus and a reproducing apparatus for the recording medium by which data can be reproduced even when a skew occurs. Reference signal areas and data areas are provided periodically on an optical disk. Each of the reference signal areas has recorded thereon a synchronizing signal, a gain reference signal and a bias reference signal as well as a phase reference signal for correction of a displacement of sampling at the trailing edge of a pit and a phase reference signal for detection of a displacement of sampling at the trailing edge of a pit.
