摘要： A Raman spectrum of a thin film which must be formed is measured in a thin-film forming step for forming the thin film on a member to be processed in an atmosphere, the pressure of which has been reduced. Moreover, the conditions under which the thin film is formed are controlled in accordance with a result of measurement of the Raman spectrum. At this time, the measurement of the Raman spectrum is continuously performed in an in-line manner while the thin film is being continuously formed on the elongated-sheet-like member to be processed. The measurement of the Raman spectrum is performed while the focal point of a probe of a Raman spectrometer is being controlled with respect to the member to be processed or while the output of a laser beam from the Raman spectrometer is being controlled. The thin film which must be. formed is, for example, a protective film of a magnetic recording medium. The protective film is, for example, a hard carbon film (a DLC film).

The first guide roller changes, while supporting a first surface of a base material conveyed by a roll-to-roll process, a conveying direction of the base material from a first direction to a second direction that is not parallel to the first direction. The second guide roller changes, while supporting the first surface of the base material, the conveying direction of the base material from the second direction to a third direction that is not parallel to the second direction. The at least one first head is disposed between the first guide roller and the second guide roller, faces a second surface opposite to the first surface of the base material, and discharges, towards the second surface, a raw material gas for self-limiting reaction deposition.

摘要： A magnetic recording medium includes a nonmagnetic support having a thickness less than 7 μm and a width of 8 mm; a ferromagnetic metal layer disposed on a surface of the nonmagnetic support; and a reinforcing layer disposed on the other surface of the nonmagnetic support. The magnetic recording medium has a flexural rigidity EI of 5.9×10−8 to 1.3×10−7 N·m (6.0×10−4 to 1.3×10−3 g·cm). The flexural rigidity EI is determined by the following equation: EI=(π/4−2/π)·W·a3/d·b×9.8×10−5 (wherein W is a load that causes an annular test piece having a radius of a cm and a width of b cm which is prepared by cutting a magnetic sheet formed of the magnetic recording medium to undergo a radial displacement d of 0.2πa).
