    Abstract: An optical recording medium initialization method for a recording medium having a plurality of optical recording layers capable of reducing initialization irregularities caused by optical interference upon initialization without deteriorating the information recording/reproduction signal characteristic of the recording layer. On a substrate (11), a second optical recording layer (12) and a first optical recording layer (16) are successively formed via an intermediate layer (17). Furthermore, on the first optical recording layer (16), a protection layer (18) is formed. At least the first optical recording layer (16) has a recording film having a phase change type recording material. In the optical recording medium initialization method, recording/reproduction light LTR is applied from the side of the protection layer (18) upon recording/reproduction. The intermediate layer (17) is made from a material having a sufficient transmittance with respect to the wavelength of the recording/reproduction light LTR and absorption with respect to the initialization light LTI. In the process of initialization by applying the initialization light LTI to the first optical recording layer (16)from the side of the protection layer (18), the initialization is performed by using a laser beam having a wavelength in the range from 200 to 400 nm as the initialization light LTI.

    Abstract: It is intended to provide a bioassay unit, etc. whereby the problem of the space distribution at the upper part of a detection part can be solved and the servo operation on a disc substrate can be stabilized. Namely, it is intended to provide a bioassay unit (U) which has at least a means wherein a biological substance (a nucleotide chain, a peptide, a protein, a lipid, a low-molecular weight compound, a liposome, etc.) as a detection subject (D) is fixed in a detection part (3) and , onto the detection subject (D) thus fixed, a target-containing solution (S) is dropped so that the detection subject (D) reacts with the target (T) to form a reaction product (R); and another means wherein the reaction product (R) is irradiated with a excitation light (P) of a definite wavelength and the fluorescence (F) thus generated from the fluorescence-labeled substance (D) is condensed with the use of a lens (5) provided in the back face (102) side of the detection part (3) to thereby detect the intensity of the fluorescence (F).
