Abstract:
A recording medium with a wobble-modulated track, and a method of and an apparatus for detecting a header region of the same. The recording medium includes a wobbled track on which a wobble signal is recorded, a header region on which header information is recorded, and a wobble-modulated track on which a wobble modulation signal obtained by modulating the wobble signal is recorded. Accordingly, the header region is reliably detected, and the reliability of header information read is increased.
