  • Optical system having a convex surface for accessing a storage medium
    Patent number: 7050381
    Abstract: An optical system for accessing a storage medium. The system combines two kinds of laser diode, abandons some unnecessary optical elements used in the prior art, and further uses a Penta prism to fold the optical path. Moreover, the optical system uses a CZBO prism to locate the two laser diodes abreast of each other. Thus, the space of the optical system is reduced, and the optical system is more compact.
