Paper Abstract

Hybrid Magneto-Optical Recording is a potential data storage technology in the future informational society. To construct a research platform for hybrid recording, a dynamic testing system is designed and built in this paper, in which 406.7nm blue laser is used for recording and 655nm red laser for focus servo. With high modularization, the computer serves as the control core for the laser external modulation, focus servo, and sample plate spinning. Each module and its function are discussed in detail in the paper. Experimental results are also given to verify the stable and smooth performance of the system, in which the key obstacle, vibration noise, is successfully surmounted.
