摘要： The present invention improves the adhesive property by pretreating under uniform conditions the substrate surface of metal, ceramics or glass etc. with a poor adhesive property, by accelerating ions under an electric field to the substrate in advance of a diamond-like film forming process. In light of the fact that a diamond-like film forming process by ionized deposition uses thermal electron ionization means and an electric potential is applied to a grid to accelerate ionized hydrocarbon ions, the present invention could attain the aimed purpose by ionizing and then accelerating a bombardment gas such as argon as a pretreatment process in the same apparatus.

摘要： Diamond-like thin films having high uniformity and high crystallinity are produced by introducing a hydrocarbon material gas into a chamber, ionizing the gas, and depositing the ionized gas on a substrate. The gas is ionized by thermionic emission from two or more files of hot cathodes, each file having a plurality of filaments arranged at substantially uniform intervals in a linear or zigzag line configuration. Each file of hot cathodes is surrounded separately by an anode at a substantially uniform distance from a respective file of the filaments.

摘要： A protectively coated article comprises a substrate of a material selected from the group consisting of alloys containing at least Co, Ni, or Fe, ceramics, and glass and which has only a slight affinity for a diamond-like thin film, an intermediate carbon layer formed on the substrate, the intermediate layer having a hardness Hv in the range from 1000 to 5000 kg/mm2, or harder than the substrate but less hard than a diamond-like thin film to be formed thereon, and a diamond-like thin film formed further thereon. The interposition of the intermediate layer permits the diamond-like thin film to be bound securely to a substrate surface which has a slight affinity for the film.

摘要： Articles having a diamond-like protective film formed thereon, each comprising a substrate of a material selected from the group consisting of alloys containing at least Co, Ni, or Fe, ceramics, and glass and which has only a slight affinity for a diamond-like thin film, an Mo film formed on the substrate, and a diamond-like thin film formed further thereon. Such articles are manufactured by a method which comprises holding a grid made of Mo close to the surface of the substrate, bombarding the grid and the substrate surface with a bombarding gas consisting of inert gas atoms of Ar or the like, thereby removing contaminants from the surface and depositing Mo atoms on the substrate surface to form an Mo film thereon, ionizing a low-molecular-weight hydrocarbon or a feed gas capable of producing a low-molecular-weight hydrocarbon upon decomposition or reaction, and then accelerating the resulting ions and depositing the same on the Mo film to form a diamond-like film thereon. The substrate is preferably a metallic mold constructed of a hardened steel. The Mo film enhances the bond of the diamond-like film to the substrate and improves the strength of the mold surface.

摘要： A magneto-optical disc includes a pit forming region and a groove forming region on a surface of a substrate and a recording layer covering the pit and groove forming regions. The pit forming region includes a row of pits having a width of 0.40-0.55 .mu.m and a depth of 600-900 .ANG. and the groove forming region includes a spiral groove having a width of 0.95-1.15 .mu.m and a depth of 600-900 .ANG.. The disc is recorded and read by using an optical head with an objective lens having a numerical aperture of 0.40 to 0.50 and directing linearly polarized laser light having a wavelength of 600 to 900 nm to the disc such that its electric field vector has a direction perpendicular to the groove and the pit row. Tracking, seeking and information retrieval can be done with minimal errors using the same laser light beam in both the pit and groove forming regions.
