    摘要： Provide is an ion trap mass spectrometer which is configured to gain an MS spectrum of only fragment data in an MS/MS analysis, thereby makes it possible to perform the analysis in a short period. For this purpose, the device is comprised of: an ionization unit configured to ionize a sample which has been separated into respective components; an ion trap unit configured to trap ions ionized by ionization unit in an electric field and eject the ions in accordance with the respective masses of the ions; a detection unit configured to detect the ions ejected from the ion trap unit; and a processing unit configured to generate an MS spectrum (mass spectrum) on the basis of data detected in the detection unit. The processing unit further configured to gain an MS spectrum of only fragment data of a target ion from a difference between an MS spectrum gained in an MS analysis made before and/or after an MS/MS analysis and an MS spectrum gained in the MS/MS analysis.

    摘要： A phase change optical disk medium includes a disklike substrate, and a recording layer formed by a laminate of a plurality of thin layers including a phase change layer. Information marks are recorded on the phase change layer by phase changes from a crystal phase to an amorphous phase and vice versa. The recording layer has tracks for recording information marks formed by groove portions and land portions respectively taking alternate concave and convex shapes. The track has an interval in range of 0.54 to 0.64 .mu.m and the recording layer has a ratio of the optical reflectance of 0.35 or less when the phase change layer has changed to the amorphous phase in case where the optical reflectance of the recording layer is 1 when the phase change layer is in the crystal phase.
