A magneto-optical recording medium having at least one of a transition metal and a rare earth metal dispersed in a dielectric material and having an easy axis of magnetization normal to a film plane.
摘要:
There is disclosed a magnetooptical recording medium, which is provided with a recording layer composed of a magnetic layer having an easy axis of magnetization perpendicular to the surface of recording layer, and a reflective layer positioned adjacent to the recording layer and composed of a mixture of a substance of a low absorbance to the light of a determined wavelength and a substance of a high reflectivity to the above-mentioned light.
摘要:
An opto-magnetic recording medium comprises a recording layer formed of a magnetic film having a readily magnetizable axis in a direction perpendicular to the surface of the film, and a reflective and phase modulating layer provided in contact with the recording layer. The reflective and phase modulating layer is formed so that the imaginary number portion (k) of the refractive index gradually increases in the direction of thickness away from that side which is in contact with the recording layer.
摘要:
An optical recording medium made up of a substrate and an electromagnetic radiation sensitive layer consisting essentially of a sulfur compound as a matrix and a substance (such as, for example, Te, Pb, Au, Sn, As, Bi, In, C) which is subjected to heat action from absorption of electromagnetic radiation and brings about optical changes by such heat action.
摘要:
An optical recording medium, having a substrate and a thin film containing a fluoride compound and a substance capable of undergoing an optical change through absorption of electromagnetic radiation (a film sensitive to electromagnetic radiation).
摘要:
An optical recording medium, comprising a substrate and a thin film which contains an iodine compound, and a substance undergoing an optical change through absorption of electromagnetic radiation.
摘要:
An optical recording medium comprising a substrate, an optomagnetic recording layer made of a magnetic film where information can be recorded and reproduced by irradiation with a light beam, and an optical recording layer which can be modified in optical properties to form guide tracks when information is recorded in or reproduced from the optomagnetic recording layer.
摘要:
In a method of manufacturing a liquid discharging head which includes a flow path forming member which has a discharge port for discharging a liquid and a liquid flow path communicating with the discharge port, and a base body having a liquid supply port which supplies the liquid flow path with the liquid, the method includes (1) forming a mold of the liquid flow path and a foundation member formed of a porous inorganic material over the base body, (2) applying an organic resin over the base body so as to cover the mold and the foundation member to form the flow path forming member, (3) forming the discharge port in the flow path forming member to form the liquid supply port in the base body, and (4) removing the mold to form the liquid flow path.
摘要:
A simplified and less costly manufacture process of a print head can be effective in preventing the peeling-off between a substrate and a flow passage forming member. In the print head, a protective layer is formed between the flow passage forming member and a heat generating portion. The protective layer contains a noble metal. On a side of the flow passage forming member, the surface of the protective layer is made of an oxide of a noble metal, except in a portion corresponding to the heat generating portion, while in the portion corresponding to the heat generating portion on the flow passage forming member side, the surface thereof is made of the noble metal.
