摘要： A a recording method and apparatus for an optical disk employs a data format having a fixed pattern sync portion in which a minimum run length of zeros and the maximum run length of zeros are not adjacent to each other. As such temperature difference caused during recording the optical disk may be made smaller, thermal stress applied upon the medium may be reduced, the deterioration thereof may be restrained, and the repetitive frequency of the medium may be improved.
