Abstract

PURPOSE:To eliminate influence due to the blurring of a laser beam by expanding the width of the laser beam in a subscan direction, setting a slit adjacently to a photosensitive medium, and cutting the width in a width scanning direction of the laser beam to be irradiated on the photosensitive medium. CONSTITUTION:A beam expandor 7 is provided in the optical path of the laser beam 2 before being made incident on a deflecting means and also, a slit plate 11 having the slit 11a conformed to a line in a main scanning direction is provided at a position adjacent to or being brought into contact with the photosensitive medium 10. And beam shape on the photosensitive medium 10 is set at a value almost equal to or a little smaller than the width of the slit in the scanning direction of the beam 2, and as for a direction intersecting orthogonally to the scanning direction of the beam 2, it is set at the value larger than the value in which the width of the slit 11a is added on the width of blurring generated in the direction, by the beam expandor 7. Also, the width intersecting orthogonally to the scanning direction of the beam 2 of the slit 11a is set at the width almost equal to the interval of the scanning line of the beam 2. In such a way, it is possible to solve actual pitch irregularity on a recording medium with simple constitution.
