ABSTRACT:
An optical data recording/reproducing device, wherein the number of reflection in an optical path of coherent light formed between a coherent light source and an optical disk is twice or a larger even number of times, and the array direction of the coherent light source and photodetectors is substantially parallel to the face of the optical disk, resulting in a smaller size in the direction corresponding to the thickness of the optical disk.
