ABSTRACT:
An optical disc system, an optical disc employed in such system, and an optical disc apparatus employed for driving the optical disc system, are disclosed. The optical disc includes plural wobbled grooves gr which include address information data. The optical disc is pre-formatted so that the wobbled grooves are formed so that the distance between neighboring grooves gr corresponds to the number of channels in an HDTV signal. For instance, two channels, CH1 and CH2, are recorded on recording lands are defined between the neighboring wobbled grooves formed at a distance of 3.2 .mu.m. Signal dots Sd.sub.1, Sd.sub.2 for the two HDTV signal channels CH1 and CH2 are recorded on either sides of each wobbled groove gr. The HDTV signals may be recorded on the real time basis and for an extended period of time.
