Signal record conditional adjustment method to optical information record medium, information record reproducing arrangement

摘要

As for signal record conditional adjustment method, front gradual sutorateji setting step and succeeding spaceIt possesses with long corresponding trailing edge adjustment step. With front gradual sutorateji setting step, without depending on immediately before space length or immediately after space length, record sutorateji which corresponds to mark length is set. With succeeding space long corresponding trailing edge adjustment step, last edge fall edge position among record sutorateji which are set with front gradual sutorateji setting step, is adjusted on the basis of immediately after space length. This succeeding space long corresponding trailing edge adjustment step just the identical quantity to evenness has the even trailing edge adjustment step which is changed last edge fall edge position of record sutorateji which corresponds to the mark which possesses the mark length above specified length, on the basis of immediately after space length.
