发明名称 Method for recording information, method for reproducing information, and information recording apparatus
摘要 A method and apparatus for recording and reproducing information to and from an optical disk. If the size of a shortest mark is made small, a signal amplitude lowers and errors are likely to occur. In order to overcome this problem, when data of asymmetric codes is written, the length of a write mark is compensated so that the shortest mark and gap have the same length.
