ABSTRACT:
There is disclosed a small lightweight optical information storage apparatus which can obtain a sufficient writing light quantity, and an optical device which can realize the optical information storage apparatus. The optical device for use in the optical information storage apparatus has a splitting surface constituted of a part of a cylindrical surface. A light emitted from a light source is passed via the optical device and directed to an optical information storage medium, and a signal light is split from a return light from the optical information storage medium by the optical device.
