In this paper, we reveal a new device for use as an optical data storage system. The system is made up of Cassegrain-like structures. The volume ($35\times 20\times 20$ mm3) of the system is the size of a pickup head used in conventional optical storage. It has compatibility with several conventional optical disk technologies. Namely, the system provides a platform for integration with compact disc (CD), digital versatile disc (DVD), Blu-ray disc (BD) and holographic systems. The full width half maximums (FWHMs) of the spot size for a CD have been measured in this system and are 0.98 and 0.95 μm in the tangential and radial directions, respectively.
