摘要： PURPOSE:To obtain a magnetic disk having high reliability and high performance by forming a protective film of a carbon layer consisting of the particles released by sputtering a graphite target and active gaseous particles. CONSTITUTION:The protective lubricating layer 14 formed by bonding CVD layers 12 and sputtered layers 13 is formed on the magnetic disk constituted by forming a magnetic layer 15 on a substrate 16. Namely, the particles released by sputtering the graphite target and the active gaseous particles (gaseous ion particles by a CVD method) generated by ionizing the gas contg. a carbon component are deposited simultaneously on the substrate 16, by which the carbon film is formed thereon. Since this film is the carbon film having the respective characteristics of the sputtered film and the CVD film in combination, this disk is improved in the surface smoothness, min. cofft. of friction, stability with lapse of time and moisture resistance.

摘要： PURPOSE:To remarkably improve the life of a magnetic recording medium by providing a magnetic layer consisting of a material having ferromagnetism, a layer consisting of an org. material and a layer consisting of carbon in this order on a supporting base body. CONSTITUTION:The org. material layer is provided as an intermediate layer between a carbon film and the magnetic layer. The carbon layer is formed by a method for forming said layer under the conditions under which electrons, ions or neutral particles having the energy enough to disconnect the bond of the org. material surface in the initial period of formation are made incident on the treated surface. The org. material to be used for the org. material layer is required to be made into a thinner film having preferably 0.1-0.001mum thickness and has preferably >=50kg/cm adhesive power. The method for forming the org. material layer includes coating, sputtering, plasma polymn, and vapor deposition methods. The exfoliation and removal of the carbon protective layer during sliding of the magnetic recording medium with a head is thereby prevented and the lubricating performance intrinsic to carbon is provided. The life of the magnetic recording medium is thus remarkably improved.

摘要： PURPOSE:To improve a remained film rate of the resist in plasma development by a method wherein at least one layer among the multi-layered coating comprising organic substances other than the lowermost layer is made to contain metal elements. CONSTITUTION:Multi-layered coatings 2, 3 comprising organic substances are formed on a substrate 1, and at least one layer 3 among such multi-layered coatings other than the lowermost layer is made to contain metal elements. For example, the coating 2 comprises polystylene, polyimide, etc., while the coating 3 comprises organic silicon high molecules, a mixture of organic metal compounds and high molecules, etc. A light or radiation 7 is irradiated onto an element 10 with those coating thus formed, thereby to effect the exposure process. Then, the upper layer 3 undergoes plasma development with plasma containing fluorine. Next, the lower layer 2 undergoes plasma development with plasma containing oxygen. When the organic thin film containing metal elements are brought into contact with oxygen plasma, SiO2, Al2O3, etc. are generated in the film and the film becomes hard to be decomposed, so that a remained film rate of the lower resist can be improved.
