ABSTRACT:
In a method of recording or reproducing data out of an optical disk of the present invention, the optical disk is includes a substrate formed with a spiral groove track and a land track formed between nearby portions of the groove track. Header information is periodically recorded in each of the groove track and land track. Beam spots are formed on the land track and groove at the same time. Data are recorded in or reproduced out of the land track and groove track at the same time on the basis of a timing determined by the header information read out of the land track and groove track. When one beam spot formed on either one of the land track and groove track is reading the header information, the other beam spot is inhibited from recording or reproducing data.
