    摘要： A magneto-optical recording medium and a method for recording and reproduction thereon are provided in order to reproduce information recorded by multi-valued recording at a high S/N ratio. Disclosed is a magneto-optical recording medium including two magnetic layers capable of four-valued recording based on four combined magnetization states. Magnitudes of reproduction signals concerning the four magnetization states, obtained upon reproduction at a wavelength λ1, are different from those obtained upon reproduction at a wavelength λ2. The two magnetic layers, on which a signal (a) is recorded, are irradiated with light beams having the wavelengths λ1 and λ2 respectively. Signals (d), (e) reproduced from respective reflected light beams are sliced by using at least one slice level to obtain two-valued or higher multi-valued reproduction signals respectively. The two-valued or higher multi-valued reproduction signals (f), (g) from the respective wavelengths are mutually subjected to logical operation to reproduce recorded information (i).

    摘要： A magneto-optical recording medium and a method for recording and reproduction thereon are provided in order to reproduce information recorded by multi-valued recording at a high S/N ratio. Disclosed is a magneto-optical recording medium including two magnetic layers capable of four-valued recording based on four combined magnetization states. Magnitudes of reproduction signals concerning the four magnetization states, obtained upon reproduction at a wavelength .lambda..sub.1, are different from those obtained upon reproduction at a wavelength .lambda..sub.2. The two magnetic layers, on which a signal (a) is recorded, are irradiated with light beams having the wavelengths .lambda..sub.1 and .lambda..sub.2 respectively. Signals (d), (e) reproduced from respective reflected light beams are sliced by using at least one slice level to obtain two-valued or higher multi-valued reproduction signals respectively. The two-valued or higher multi-valued reproduction signals (f), (g) from the respective wavelengths are mutually subjected to logical operation to reproduce recorded information (i).

    摘要： A method of detecting a reactive metabolite which comprises steps of conducting a metabolic reaction of a test compound in the presence of two labeled nucleophiles, and detecting the label of the nucleophiles bound to the reactive metabolite, and a method of detecting a reactive metabolite which further comprises separating liquid layer using ammonium acetate to obtain an organic layer after the aforementioned reaction step are disclosed. In these detection methods, a reactive metabolite can be quantitatively detected by easy preparation. Furthermore, generation of a false positive signal can be prevented, and generation of a false negative signal can be decreased. Accordingly, screening of a test compound can be efficiently performed with higher accuracy.
