It is an object of the present invention to provide an information recording method for recording information in a data rewritable type optical recording medium having a plurality of information recording layers, which can form recording marks having good shapes. In the information recording method according to the present invention, information is recorded in an optical recording medium 10 having at least a stacked L0 layer 20 and L1 layer 30 by projecting a laser beam thereonto whose power is modulated between a plurality of powers including at least a recording power (Pw) and an erasing power (Pe) via a light incidence plane 13a. When information is recorded, λ/NA is set to be equal to or shorter than 700 nm, where λ is a wavelength of the laser beam and NA is a numerical aperture (NA) of an objective lens, and a ratio (Pe/Pw) of the recording power and the erasing power when information is to be recorded in the L0 layer 20 is set to be smaller than that when information is to be recorded in the L1 layer 30.

An electrical testing substrate unit includes a multi-layer ceramic substrate formed of mullite and a borosilicate glass as predominant ceramic components. In the multi-layer ceramic substrate, the borosilicate glass contains an alkali metal oxide in an amount of 0.5 to 1.5 mass %. The multi-layer ceramic substrate has a mean coefficient of linear thermal expansion having a value of 3.0 to 4.0 ppm/° C. between −50° C. and 150° C. A thermal expansion coefficient, α1, of the multi-layer ceramic substrate as determined at a particular temperature and a thermal expansion coefficient, α2, of a to-be-tested silicon wafer as determined at the same temperature silicon satisfy a relation: 0 ppm/° C.

An information readout method for an optical information medium comprising an information recording layer having pits or recorded marks representative of information data involves the step of irradiating a laser beam to the information recording layer through an objective lens for providing readings of the pits or recorded marks. When the laser beam has a wavelength λ of 400 to 410 nm, the objective lens has a numerical aperture NA of 0.70 to 0.85, and the pits or recorded marks have a minimum size PL of up to 0.36λ/NA, readout is carried out at a power Pr of at least 0.4 mW for the laser beam. When the laser beam has a wavelength λ of 630 to 670 nm, the objective lens has a numerical aperture NA of 0.60 to 0.65, and the pits or recorded marks have a minimum size PL of up to 0.36λ/NA, readout is carried out at a power Pr of at least 1.0 mW for the laser beam. Pits or recorded marks of a size approximate to the resolution limit determined by diffraction can be read out at a high C/N.

A rewritable phase-change optical recording medium is provided, which includes a substrate, a first information layer, a spacer layer, a second information layer, and a cover layer. The second information layer includes a recording film containing Sb as a main component and V or V and In as second components. When an amorphous mark formed in the recording film is irradiated with a reproduction beam, crystallization of the amorphous mark occurs only in a central portion in the width direction of the amorphous mark. The width direction is orthogonal to the scanning direction of the laser beam. The recording film is formed of a material that exhibits a change in degree of modulation of 5% or less when recorded information is repeatedly reproduced. The change in degree of modulation is a change from when the number of times of reproduction is 100,000 to when it is 400,000.
