摘要： An optical fiber array is constructed by using a plurality of laser modules, which guide a laser beam emitted from a semiconductor laser of a blue color wavelength to an optical fiber, such that beam emitting ends of respective optical fibers are aligned in one row at an equal interval, and the laser beam being output from the optical fiber array is used as a multibeam of an optical recording apparatus. A relative refractive index difference of the used optical fiber is set between 0.1% to 0.2%, and a core diameter is set to 4.5 μm or less, and also a mode field diameter of the optical fiber, i.e., a diameter of a beam spot emitted from the optical fiber is set to 3 μm or more.

摘要： An optical recording apparatus includes an optical system, a photosensitive drum and a rotational mechanism. Multibeam laser light is focused through the optical system to form an image as a column of image-forming beam spots on the photosensitive drum. The column of image-forming beam spots is arranged obliquely on the photosensitive drum and scanned to perform optical recording. The optical system includes a resolution converting lens system which is detachably attached into the optical system. The rotating mechanism adjusts rotation of the resolution converting lens system around an optical axis thereof. The resolution converting lens system is rotated by the rotating mechanism to change of resolution of the recording image. The resolution converting lens system is attached into and detached from the optical system to change of resolution of the recording image.

摘要： An optical recording apparatus includes a light-transmitting diffraction grating at a front focus of an imaging lens and a multi-channel acousto-optic modulator provided at a back focus of the lens. An angle formed between a plane formed by diffracted beams emerging from the lens and a revolution surface of a rotating polygonal mirror is set to be equal to an angle at which the beam diffracted by the multi-channel acousto-optic modulator emerges to be incident on the mirror. The diffracted beams are incident on the imaging lens to satisfy a predetermined condition.
