Research for a new 3 dimensions storage system

摘要

A optimum design scheme for a new 3 Dimensions Magneto-Optical Disc information storage system is proposed. By the use of the Polarization Preserving Fiber (P.P.F) integrated optical head, the small objective lens of the P.P.F optical head can be moving at high speed, the average access time of the storage system can be reduced effectively. The wave division multiple technology can be used to realize multi-wavelengths optical fiber signals transmission in parallel mode, so the 3 dimensions storage system possesses the advantages of huge density, and the the access time will be further decreased. According to the laser diffraction theory, a optical expert system software is set up to analyze the aberrations of the integrate optical head, and to compute the pick-up signals by computer simulation.
