Patent abstract
There is provided an apparatus capable of switching between a laser that emits light having a wavelength suitable for detecting samples and a laser required for reading traced data, while an analysis optical disc is being traced. In an analyzer in which an analysis disc having a sample to be analyzed which is located in a part of its track is irradiated with laser light to read the state of the sample, a selector switch alternately selects a laser having a wavelength for reading data represented by bits or wobble grooves on the disc and a laser having a wavelength suitable for detecting a sample, in response to an instruction from a control unit.
