Magneto-optical recording disk drives have been introduced into the marketplace by several companies. This paper reviews the basic technology which makes these drives possible and then describes on-going research which is expected to lead to future advances. New technologies such as direct overwrite recording, optical heads using laser diode arrays for parallel track readout, shorter wavelength lasers, advanced signal processing, improved modulation and error correction codes, and lightweight heads using optical fibers and/or integrated optical components are expected to lead to order of magnitude improvements in storage densities and data rates, as well as substantial improvements in access times.

This paper brings forward one concept of holographic storage of multi-level digital data at first. It is that each pixel includes more information than 1 bit, which means that a multi-level digital data image provides more information than a binary digital data image with the same pixels. So, the capacity will be increased with this technology Furthermore, some aspects of holographic storage of multi-level digital data, such as the multi-level coding, storage characters and the quality of the stored image are debated. Finally, we research this holographic storagetechnology by experiment.

Multi-wavelength and multilevel (MWML) opticalstorage with photochromic media is a novel technology that can increase storage capacity and transfer rates significantly. Signal processing and coding methods for the MWML storage channel are introduced in this paper. Two-dimensional codes with parallel detection and equalization are studied to increase storage capacity and combat the crosstalk between different wavelength materials. Multilevel amplitude modulation and M-ary runlength-limited (RLL) codes are described and compared for achieving higher coding capacity. The novel MWML recording technology has the potential to be applicable for the next generation opticaldatastorage.

The readout of photochromic multi-wavelength storage was analyzed, and its model was established in this paper, with the disk reflectivity and the recording information distribution optional. The luminous power of the readout was divide into two parts: the part without the disturbance of other materials and the reading crosstalk. The expressions of them were presented, which were useful for the further analysis of the crosstalk and the crosstalk suppression method.
