Introduction to the Issue on Advanced Optical Storage Technologies
E
VOLVING INFORMATION processing applications previously found only in the realm of supercomputers are now rapidly moving to the desktop, creating a strong demand for cost effective secondary storage systems offering high capacity, high data transfer rate, and short access times. In addition, multimedia file servers, data warehouses, and data centers for network-based computing often require capacities in the 10–100-Tbyte range, and this may grow into the petabyte range in the near future. Many current and future applications in medicine, industry, entertainment, and the military must process image rich data and manipulate large data blocks. This is driving the need for systems that can provide fast data transfer rates and ease of transport (including removability) for distribution of large data files. On the other hand, transaction processing and data warehousing applications often need to search and process data in smaller blocks and access time to retrieve individual blocks of data is paramount. Optical disk media has typically been the most cost effective random access means of providing high-capacity highreliability removable storage. The recently introduced digital versatile disk (DVD) standard is likely to address the immediate optical storage demand, and magnetooptic and phase-change technologies are being optimized for improved performance, but the path to the next-generation of optical storage (past 100 Gb/in areal density) is less clear. A variety of advanced optical storage techniques and technologies are being explored, including volume holographic, multilayer,
multilevel, multiwavelength systems, together with advanced light sources, detectors, actuators, and packaging. This issue of JSTQE provides a “snapshot” of this rapidly evolving field, detailing progress and plans for both magnetooptic and phase-change optical disks, highlighting several holographic techniques for storage and correlation, discussing detection and channel processing issues for page-oriented readout with arrays of detectors, and presenting results of spectral-hole burning storage in quantum dots. Our thanks go to the reviewers for their timely and constructive criticisms, and to Mrs. Fran Jetko, Supervisor, LEOS Publications, for her kind assistance in coordinating this publication.

Frederick B. McCormick, Jr. (S’82–M’83) received the B.S.E.E. degree from the University of Washington, Seattle, the M.S.E.E. degree from Georgia Institute of Technology, Atlanta, and the Ph.D. degree in applied physics from the Heriot-Watt University, Edinburgh, U.K. In the Photonic Switching Department at AT&T Bell Laboratories, he investigated the use free-space optical interconnections (FSOI) for photonic switching and optical computing, using nonlinear Fabry–Perot etalons, Symmetric-Self-Electrooptic Effect Devices, and FETSEED “smart pixel” processing arrays. His research included optical system design, packaging, and testing of six prototype FSOI switching systems. Since joining Call/Recall, Inc. and the faculty of the University of California at San Diego in 1994, he has developed 3-D optical drive systems for two-photon 3-D memories materials and participated in the development of optically interconnected 3-D computer systems. This work has demonstrated 100 data layer 3-D recording reading and four portable ROM cube and disk drive systems using this twophoton media. He holds seven patents, has published over 80 journal and conference papers, and four book chapters. Dr. McCormick is a member of Tau Beta Pi, the Optical Society of America, SPIE, and was an IEEE Communications Society Distinguished Lecturer from 1992 to 1993.
Pierre Ambs received the M.S. and Ph.D. degrees and Doctorate d’Etat from the Universit´e de Haute Alsace, Mulhouse, France. He is a Professor of Electrical Engineering at the Universit´e de Haute Alsace. His research interests include optical and computer-generated holography, optical pattern recognition, optical storage and their applications to optical processing and computing. Dr. Ambs is a member of SPIE, the European Optical Society, and the Soci´et´e Fran¸caise d’Optique.
Yoshinobu Mitsuhashi was born in Japan in 1940. He received the B.S. degree in control engineering and the Ph.D. degree in electronics engineering from Tokyo Institute of Technology, Tokyo, Japan, in 1964 and 1986, respectively. In 1964, he started to study optical information processing technology at the Electrotechnical Laboratory. During 1972–1973, he was a Research Associate at the Department of Electrical Engineering, Carnegie Melon University, Pittsburgh, PA. In 1991, he joined Nippon Sheet Glass Co., Ltd. and is now a general manager of Fiber Optics Division. Since 1984, he has worked in standardization of optical disk cartridges and has served as the chairman of ISO/IEC JTC1/SC23 from 1993 to 1997. He is currently a chairperson of organizing committee of ISOM (International Symposium on Optical memory). He is a member of SCEJ, JSAP, IEICE, and the Optical Society of America.
