Provided is a recording apparatus and method for recording a mark on a recordable recording medium by using an optical pickup having a light source (11) and an objective lens (15) for focusing light emitted from the light source (11) as a light spot on a recording surface of a recording medium. When recording on a rewritable recording medium, the size of the light spot formed on the recording surface of a recording medium is increased more than when recording on an only once writable recording medium and/or reproducing from a recording medium. Accordingly, when recording on a rewritable recording medium, the size of a light spot is enlarged more than when recording on an only once writable recoding medium and/or reproducing from a recording medium. Thus, when a mark is recorded on the rewritable recording medium, the erasing rate of an existing recorded phase-change mark is increased to improve the overwriting characteristics. <IMAGE> |
