| Abstract: | Reflectance is one of the important characteristics of Magneto Optical (MO) disk, which determines the Signal to Noise Ratio (SNR) of the output signal of MO together with Kerr angle of MO disk. It is important to test the reflectance of MO disk in the process of development and production of MO disk. A new automatic two channel quick measurement method is proposed to test the reflectance of MO disk. The error sources of MO disk measurement instrument are discussed, and optimization is made to enhance the measurement accuracy of MO disk measurement instrument. |
