By this method, the specimen (H2NR) forms a luminous compound, for example, as shown by formula I . When the specimen is a mixture of D and L or a racement, two kinds of diastereomers are mutually generated as represented by formulae II, III. These diastereomers are subjected to liquid chromatography to be optically split to detect fluorescent intensity or absorbancy of each of them. When the specimen contains only one of D and L, detection is performed without separating the same. By this method, qualitative analysis is enabled simply with high sensitivity.

Abstract: PURPOSE:To obtain uniform magnetic recording and reproducing characteristics without variations in output by forming an Al layer with a specific film thickness between a substrate and a magnetic recording layer with regard to a medium formed in said recording layer on said substrate finished specularly on its surface by polishing. CONSTITUTION:The substrate 2 consists of an Al plate 2a plated on one side surface to form a NiP layer 2b, and the surface of the layer 2b is polished with specular finishing. Consequently, the polishing surface of the layer 2b has polishing scars 5 in a fixed direction. Then, the Al layer 3 with >=50Angstrom  film thickness is formed on the layer 2b by sputtering, and moreover the magnetic recording layer 4 consisting of a Cr layer 4a and a Co alloy layer 4b is formed on the layer 3. Thus, by forming the Al layer 3 between the substrate 2 and the layer 4, an effect of the polishing scars 5 is eliminated by the layer 3, and the magnetic characteristic of the layer 4 is isotropic in the in-surface direction. By this method, the uniform magnetic recording and reproducing characteristics without variations in output can thus be obtained.
