Abstract
Holographic data storage system is a promising candidate of the next-generation of storage equipment. However, conventional technologies (called 2-axis holography) still have essential issues for commercialization of products. In this paper, we introduce the collinear holography that can produce a small, practical data storage system more easily than conventional 2-axis holography. In this technology the information and reference beams are displayed co-axially by the same SLM. With this unique configuration the optical pickup can be placed on one side of the recording media. The special media structure uses a pre-formatted reflective layer for the focus/tracking servo and for reading address information. It also uses a dichroic mirror interlayer for detecting holographic recording information without interfering with the preformatted information. A 2-dimensional digital page data format is used and the shift-multiplexing method is employed to increase recording density.
