Differing from the storage of image on the optical disk in series, a new method for realizing image parallel storage is presented, based on the theory of holographic optical disk storage. The image parallel readout architecture is described, and the specified optical disk holograms are designed by our proposed iterative search algorithm. The experiment results have demonstrated the image parallel storage technique.

The use of organic compounds as optical storage materials have been receiving more and more attention due to their easy preparation, low cost and tunable properties. In this paper, research results on the application of organic dyes and organo-metallic compounds as optical recording media, such as write-once media, rewritable media, and photochromic media are presented, and preparation technologies of the recording thin films are outlined and discussed.

A dual beam recorder for high density format has been developed. The recorder features remote control of size and mutual distance of both recording spots, a special beam pointing control system, and a high accuracy, laser interferometer controlled, radial drive. The recorder can switch between very dissimilar formats without intermediate alignment. The performance of the recorder has been shown for DVD, MO, and even higher density formats. Track pitches down to 0.7 micrometers have been realized.

Multimedia consumes a vast amount of storage, even when compressed. This requirement couples with the continual explosion of media availability and the human desire to access more information, makes multimedia servers the inevitable repository for many applications. In this paper we describe technology for multimedia data storage. We discuss: the choice of storage media, disk scheduling, data placement in the media, the file system of the storage server, and the reliability and availability of the multimedia storage server. As a summary, we give an implementation of our project ATM-Based Multimedia Storage System in the final part of this paper.

Effects of vacuum annealing on the coercivity in sputtered and evaporated Pt/Co multilayer films were detailedly investigated. Our experimental results showed that the coercivity experienced an initial increase and a subsequent decrease with the process of annealing. The saturation magnetization decreased slowly at initial annealing stage and then dropped drastically when the annealing temperature was further raised. The coercivity variation after vacuum annealing can be explained by the improvement of f.c.c. (111) texture and the reduction of Co layer thickness.
