ABSTRACT:
An optical pickup and an optical recording and/or reproducing apparatus using the optical pickup are provided. The optical pickup includes: a light source; an optical bench on which the light source is mounted; a focusing member including an objective lens, focusing light emitted from the light source to form a light spot on an optical information storage medium; and an optical path forming member having a transparent block that includes a light entrance/exit surface on which the optical bench and the focusing member are arranged, a first reflection surface, and a second reflection surface opposing the first reflection surface, where the optical path forming member directs the light emitted from the light source toward the objective lens by reflecting the light emitted from the light source on the first and second reflection surfaces. The optical pickup satisfies the requirement for smaller, slimmer design and can be integrated using semiconductor manufacturing processes.
