High SNR single wavelength readout for quadri-valued MO recording by detecting both magneto-optical rotation angle and ellipticity

In order to acheive a high signal-to-noise (SNR) readout method for a double-layered magneto optical (MO) disk we have proposed a new method to detect both MO rotation angle and on single wavelength readout. A double-layered MO disk was read by using the new method.
