Abstract

An actuator structure and servo technology for a Holographic Versatile Disc (HVD™) drive system, based on Collinear™ Technology is proposed. Servo technology is introduced to control the objective lens position precisely to the disc surface, eliminating the requirement for a vibration isolator. Holographic Versatile Disc (HVD™) system using Collinear™ Technology, a new technology for HISS, is proposed and demonstrated by OPTWARE Corporation (1). This technology can produce a small, practical HISS more easily than conventional 2-axis holography. In this paper, we propose the servo technology that is widely used in the optical disc (like CD and DVD) and is applied to HVD™ using Collinear™ Technology. The construction of the actuator being employed in this technology, and the structure of the HVD are presented.
