By use of optical holographic theory, achromatic opticalsystem on recording holographic BSG mask is designed. Its aberration is analyzed by using ZEMAX.
The solutions for optical mass storage system and their principles are analyzed briefly, based on which, the key technologies for the improvement of the recording density are discussed.
