ABSTRACT:
It is an object of the present invention to reduce a data error ratio in the mark edge recording method. In this invention, a corrected value of a record pulse is set by checking the data recording characteristics of an optically recording medium. For this reason, it is possible to adjust a length of a record mark to a specified value as well as to suppress errors such as data errors when data is regenerated.
