摘要： A method of measuring a terahertz wave includes the steps of: starting input of a pulse signal showing that scale marks have been detected, which are arranged at equal intervals along a moving direction of a movable stage which can move in a direction in which an optical path length of incident pulse light is contracted or extended; and taking signals outputted at pulse intervals of the pulse light from a terahertz wave detecting section by synchronizing the timing with the pulse signal.

摘要： An optical recording medium master disc exposure apparatus comprises a modulating means 3 for modulating intensity of light from an exposure light source 1 in response to recording information and a focusing optical system 9 for focusing the light modulated by this modulating means 3 on a photoresist 12 on an optical recording medium master disc 11 to thereby pattern-expose the photoresist 12 in response to recording information. The exposure light source 1 is composed of a ultrashort wave pulse laser with a repetitive frequency of an integral multiple ranging from 1 time to 20 times as high as the clock frequency of recording information. This optical recording medium master disc apparatus includes an external synchronizing mechanism to vary the resonator length of this ultrashort wave pulse laser to mode-lock the repetitive frequency of the ultrashort wave pulse laser in synchronism with the clock frequency to cause the ultrashort wave pulse laser to emit pulses, and hence miniscule pits can be formed with high accuracy.

摘要： A dielectric part 4 comprising a nitride layer 7 and an oxide layer 8, laid one upon the other, is formed on a data-recording layer 3. A light-transmitting layer 5 is boned with adhesive to the dielectric part 4. Since the dielectric part 4 is interposed between the data-recording layer 3 and the light-transmitting layer 5, the organic material of the data-recording layer 3 does not diffuse into the adhesive that bonds the light-emitting layer to the dielectric layer 4. Additionally, the data-recording layer 3 is not deteriorated due to the oxygen plasma generated during the process of forming the oxide layer 8, because the oxide layer 8 is provided on the nitride layer. Since the nitride layer 7 has a thickness of 10 nm or less, it does not influence optical enhancement effect.

The first protective dielectric layer is a nitride film having a film thickness such that the product of its refractive index and the film thickness is not less than 0.2 and not more than 0.35 times the wavelength of the laser light employed. The second protective dielectric layer is a nitride film having a film thickness such that the product of its refractive index and the film thickness is not less than 0.1 and not more than 0.15 times the wavelength of the laser light employed. The the reflective metal layer is a metal layer having a film thickness of not less than 500 .ANG. and not more than 1000 .ANG., with the metal being electro-chemically less noble than the material of the recording magnetic layer and having a reflectivity at the boundary with the second protective dielectric material of not less than 70%.
