Abstract

PURPOSE:To obtain an optical information recording medium with high sensitivity and long life by forming a recording film which contains low melting point metals, and C, P, and H on a substrate. CONSTITUTION:On a glass or synthetic resin substrate 1, a recording film 2 which contains 5-40 atom % C and 1-50 atom % P when the composition is represented by the formula, where H is determined by the formation of the recording film 2 and M is a metal such as Bi (fusion point; 217 deg.C), Cd, and In having a 25-600 deg.C fusion point or alloy such as InSb (535 deg.C). For the formation, said metal is used as a target, and reactive sputtering is carried out in mixed gas of CH4 and PH3. Consequently, the recording film becomes hard to deteriorate owing to O2 in the air and humidity, etc., thereby obtaining a recording medium which has long life and high sensitivity.

。However, when sBj is left in the atmosphere, it is oxidized by oxygen and moisture, and when used as a transparent film, the film is extremely thin, about 700 mm thick, so the film becomes oxidized. The sensitivity deterioration of the film due to the increase in transparency caused by this is significant. In other words, when the film becomes molten, its melting and evaporation temperature rises, and it becomes transparent, resulting in less light absorption, and the energy involved in pit formation increases, leading to a decrease in sensitivity. For example, when the apparatus is operated in an atmosphere of 70 DEG C. and relative humidity of 85 g6, the sensitivity decreases by about 20 degrees in about 5 hours, and by about 50% in about 15 hours.

Although the method of coating B11k with a stable inorganic substance is effective, it has not been put into practical use due to decreased sensitivity and high cost.On the other hand, in the case of plastic coating, it has the advantage of low thermal conductivity and little loss of sensitivity. Allows oxygen and water to permeate relatively easily.
