Abstract: A magnetic recording medium includes the following: an electrical insulating film; a ferromagnetic metal thin film, a hard carbon film, and a lubricant layer formed on the surface of the electrical insulating film in the indicated order; and a back-coating layer formed on the back of the electrical insulating film. The number of dropouts is not more than 200, and the still life is not less than 10 minutes. A method for manufacturing the magnetic recording medium includes the following: bringing the ferromagnetic metal thin film into contact with an outermost layer of a resistance roller, the resistance roller including a columnar or cylindrical conductive axis, an innermost layer, and the outermost layer, wherein a portion that is formed around the conductive axis and defined between the innermost layer and the outermost layer has a resistance gradient in its thickness direction so that a resistance is low on the innermost layer side and high on the outermost layer side; supplying a reactant gas of hydrocarbon to a decompression chamber while applying a voltage to the conductive axis of the resistance roller; and forming the hard carbon film on the ferromagnetic metal thin film by plasma CVD. This magnetic recording medium can maintain high reliability even under severe working conditions.

Abstract: In a high intensity discharge lamp, at least one of an arc bend amount and an apparent width of arc is controlled by a simple configuration at low cost. A high intensity discharge lamp system 110 has a high intensity discharge lamp 111 and an operating circuit 113 for driving the high intensity discharge lamp 111. In the high intensity discharge lamp 111, a rare gas and a filling material 136 containing a metal halide as a light generating substance are enclosed in the arc tube 121 provided with a pair of electrodes 122a and 122b. The lamp system is disposed such that the line connecting the electrodes 122a and 122b is horizontal, and by applying a magnetic field having a vertical magnetic flux thereto and by varying the frequency of alternating current for driving the high intensity discharge lamp 111, at least one of an arc bend amount and an apparent width of arc can be easily controlled.
