When a wavelength of a first laser beam with which a first recording medium including a first recording layer is recorded and reproduced is indicated as λ1 (nm), a wavelength of a second laser beam with which a second recording medium including a second recording layer is recorded and reproduced as λ2 (nm), the relationship between the wavelength λ1 and the wavelength λ2 is set to be expressed by 10≦|λ1−λ2|≦120. The first recording layer has a light absorptance ratio of at least 1.0 with respect to the wavelength λ1. The light transmittance of the first recording medium with respect to the wavelength λ2 is set to be at least 30 in both the cases where the recording layer is in a crystal state and in an amorphous state. In order to record and reproduce the optical multilayer disk with the above-mentioned characteristics, a multiwavelength light source with the following configuration is used. Wavelengths of fundamental waves with different wavelengths from injection parts formed at one end of a plurality of optical waveguides, which satisfy phase matching conditions different from one another and are formed in the vicinity of the surface of a substrate, are converted simultaneously, and the first and second laser beams are emitted from emission parts formed at substantially the same position at the other end of the optical waveguides.

Apparatus and method for measuring transmittance

A device to measure the amount of light able to transmit through a liquid. The device uses a light detector and light source mounted to a support mechanism such that the detector and light source define a path of light emitted by the light source and detected by the detector. The device uses a structure designed to surround a liquid to be tested such that the structure allows light to transmit through the structure and the liquid. An actuator engenders relative motion between the support mechanism and the structure such that at certain times the light propagating between the light source and the detector passes substantially through the structure and the liquid to be tested such that the amount of light able to transmit through the liquid is detected by the detector, and at other times the light propagates directly from the light source to the detector without passing through the structure or the liquid such that the amount of light emitted from the light source is directly detected by the detector. A microprocessor then uses the two sets of detector readings to allow the transmittance measurement of the liquid to be compensated for errors introduced by drift and fluctuations in the amount of light emitted by the light source and also by drift in the light detector and electronics. Such fluctuation and drift is very common in light sources and is due primarily to changes in temperature and imperfections in the light source itself and the power supply.
