Paper Abstract

CollinearTM Holography, proposed and demonstrated by OPTWARE Corporation, can produce a small, practical holographic versatile disc (HVDTM) drive system more easily than conventional 2-axis holography. With CollinearTM technologies' unique configuration the optical pickup can be designed as small as DVDs, and can be placed on one side of the recording media. As servo technology is being introduced to control the objective lens to be maintained precisely to the disc in the recording and the reconstructing process, a vibration isolator is no longer necessary. Experimental and theoretical studies suggest that the holographic material is very effective in increasing the recording density of the system. A high density data recording of CollinearTM Holography by reducing optical noise is also demonstrated.
