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.
Measurement technology plays an important role in the area of optical storage, a multifunctional quasi-dynamic static
optical recording tester, which can also be used as nanometer laser direct writing lithography system, is designed and
constructed for optical storage in this paper. The primary characteristics of the system are presented in detail, some
experimental results are also given to show that the tester perform successfully, acting as a research platform for both
optical storage and laser direct writing lithography.
