    Abstract: In a recording technique in which a plurality of light spots are simultaneously formed by using an ultra-short pulse laser and a spatial phase modulator, and a plurality of recording dots having refractive indexes different from those of the vicinities thereof are formed inside a recording medium, it is hard to make recording quality and a recording density compatible. Therefore, a plurality of dots are recorded at a predetermined dot pitch, and then other dots are recorded between the recorded dots.

    Abstract translation: 在其中通过使用超短脉冲激光器和空间相位调制器同时形成多个光斑的记录技术中,并且在记录介质内形成具有与其附近不同的折射率的多个记录点 ,难以使记录质量和记录密度相容。 因此,以预定的点间隔记录多个点,然后在记录的点之间记录其他点。
