Abstract:
An optical recording method includes the steps of: encoding record data to generate encoded data which is a combination of marks and spaces; classifying the encoded data according to a combination of a mark length of the mark, a space length of a first space that immediately precedes the mark, and a space length of a second space that immediately succeeds the mark; generating a write pulse train for forming the mark, in which at least one of a leading end edge position, a trailing end edge position and a pulse width of the write pulse train is changed according to a classification result; and irradiating the optical disc medium with the write pulse train generated to form the plurality of marks on the optical disc medium.
