摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of the irregularity in the reflectivity caused by the irregularity in superimposing beam spots by using the beam spot having two strong peaks in the width direction as the method to increase the width in the direction of the beam advance. SOLUTION: The laser beam emitted from a high output power semiconductor laser 10 having a wavelength of 810 nm (a maximum output power of 1 W) is made into collimated light beams by a collimating lens 11, divided into two beams by a prism 13 and two beam spots 9 are obtained by an objective lens 12. Then, a disk is rotated at a constant speed of 10 m/S (a constant linear velocity) and the spots 9 are irradiated under the control so that focuses are made on a recording film (an irradiated power: 850 mW). At that time, the length of the spots 9 (at the half power point of the peak power) is approximately 50 μm. Moreover, the directions of the major axes of the spots 9 are made approximately orthogonal with respect to the recording track direction. The distance between two peaks is set to 2 μm and the power strength of the peak, which is advancingly irradiated time wise, is set higher.
