ABSTRACT:
A method of recording data as presence/absence of marks on an information recording medium includes a step of obtaining data pieces, each of which has size of one block and is made by adding error-correction-purpose data to information data, a step of attaching to each of the data pieces a synchronizing signal that includes a portion having the marks and a portion having no mark, a step of recording the data pieces on the information recording medium in units of the one block inclusive of the synchronizing signal, and a step of placing a concatenation point at a predetermined position within the synchronizing signal when adding, or writing in an overwriting manner, the data pieces in units of the one block, the concatenation point defining a position at which said adding or said writing starts.
