A method of recording data on an optical recording medium includes forming a mark or a space using a recording waveform which includes a DC record pattern, and an erase pattern that includes a multi pulse. According to the method and an apparatus using the method, the distortion of a mark can be prevented and the shape of a mark can be improved, thereby increasing recording/reproducing characteristics.
