The method to control beam comprises steps of projecting a source beam to a disk and reflecting a reflected beam passing through the disk by using a disk shaped beam splitter which reflects a source beam and passes through a reflected beam which arrives at a disk and is modulated on a recording surface of the disk; compensating the astigmatism by generating reverse astigmatism corresponding to the astigmatism generated by refraction the reflected beam makes as it passes through the beam splitter; and projecting the reflected beam of which the astigmatism is compensated to a light receiving element.
