ABSTRACT:
An optical recording apparatus includes a plurality of laser modules, an optical fiber array unit, a photosensitive member, and an optical system. Each laser module includes a light source and an optical fiber. The optical fiber array unit bundles a plurality of optical fibers to form an optical fiber array. The photosensitive member has a photosensitive surface. The optical system scans laser beams outputted from the array of the optical fiber array in a first direction on the photosensitive surface, the laser beams forming dots aligned in a second direction to form an angle with respect to the first direction. A relationship of 2ωF>2ωD(PF/PD)sin[tan−1(2m·Δθ)] is established, where 2ωFis a mode field diameter of the laser beams outputted from the optical fiber array, 2ωDis a spot diameter of the laser beams on the scanning surface, PFis a pitch of the output faces of the optical fibers, PDis a pitch of scan lines on the scanning surface, m is the number of the laser beams, and Δθ is adjusting resolution for the angle of the array of the laser beams on the scanning surface.
