Abstract
An apparatus for reproducing of data recorded on a disc type recording medium having alternatively a first region with previously recorded clock information and a second region with data information along the circumferential direction of the disc in the form of tracks. A clock signal re-generated on the basis of the clock information read from the recording medium is delayed by a preselected delay time during at least the reproducing period of the second region. Thus, the apparatus can operate stably regardless of the variations of the sensitivity of the disc and the recording condition such as intensity of the recording laser power or the like.
