The reason is... The sulfur component of zns-sI〇2 is diffused into the Zns of the protected layer. In other words, in order to increase the capacity and record at high speed, a pure Ag or Ag alloy having high reflectivity and thermal conductivity is used for the reflective layer, but the reflective layer is disposed adjacent to the protective layer Zns_si02. Therefore, due to the diffusion of the & component, the corrosion of the pure Ag or Ag alloy reflective layer is also deteriorated, which causes the deterioration of the characteristics such as the reflectance of the optical information medium. In order to prevent the diffusion of these sulfur components, the reflection Between the layer and the protective layer, the recording layer and the protective layer, an intermediate layer containing nitride or carbide as a main component is provided. However, due to an increase in the number of layers, the production amount is low or the cost is increased.

By replacing the protective layer material ZnS_Si〇2 with a material containing no sulfide and containing only an oxide, deterioration due to diffusion of sulfur to the adjacent reflective layer, recording layer, or the like can be suppressed, and the same degree as ZnS_Si〇2 can be ensured. The optical properties and amorphous stability are able to form a film at a high speed. In this way, the characteristics of the optical information recording medium are improved and the productivity is improved. [Cross-application method] The wire A of the present invention is characterized in that the tin-phase of the tin oxide phase (110) is strong, and the oxide or composite oxide other than tin oxide is stored. 1263686 & By adding such a compound containing zinc oxide as a main component, "targeting conductivity" can be used for DC sputtering (sputtering to form a film. DC sputtering is compared with RF sputtering) The speed is fast, the sputtering efficiency is better and better. The 'Shen@Mine's device is cheap, easy to control, and has the advantage of 8 power consumption. Because the film thickness of the protective film itself can be thin, it can improve production hygiene. In addition, as described above, the sputtering target of the present invention has a relative density of 90% or more and a volume resistivity of at least Am, and the use of the dry material improves productivity and sub-payment. The material has a remarkable effect of an optical recording medium which can be manufactured at a low cost and stably and which has a disc protective film. This is an optical information recording medium (protective film) which can form a film uniformly and has excellent characteristics. Furthermore, using the invention (4) The film formed by the bar is formed into a structure of the optical information recording medium, and is disposed adjacent to the recording layer or the reflective layer. However, as described above, since ZnS is not used, there is no pollution caused by s, and sulfur components are not diffused. The sandwiched recording layer of the protective layer has a remarkable effect of deteriorating the deterioration of the recording layer. Further, in order to increase the capacity and record high speed, a pure germanium or Ag alloy having high reflectance and high thermal conductivity is obtained. When it is used for a reflective layer material, the sulfur component does not diffuse to the adjacent recording layer material. The towel can also prevent the deterioration of the reflective layer material and the reflectance of the optical information recording medium, and has an excellent effect. Also... 1263686 has good sputtering properties. The transmittance of the bond-killing film tends to decrease with the increase of Sn〇2, but it also reaches 88~95% (633nm) and the refractive index is 22~2. ·4, and still have no specific crystallization peak, and have stable amorphous (ΐ ι 15). In this embodiment, the gram is not used because of the diffusion and contamination of sulfur. Lead to deterioration of the characteristics of optical information recording media Compared with the comparative examples described later, the transmittance of the film-forming sample, the refractive index, the stability of the amorphous state, the bar density, the volume resistivity, and the film formation rate all showed good values, and DC money plating can be performed. Example 1-5 The material of the raw material powder composition and the composition ratio which are different from the conditions of the present invention are prepared, and a ZnS is prepared in the same manner as in the case of the same example. The target was used to form a sputter film. The results are also shown in Table 1. The ratios and comparative examples of the present invention are omitted. For example, Comparative Example 3, 'Example 5' The resistor block is higher, so the lamp is plated with Μ曰 (4) through the DC (10) and the method is increased by χ θ UA. The material is extended by 1, and there is no furnace, especially the comparative example 5 contains a large amount of ZnS. Dangerous material. In Comparative Example 1, 1 - 1.3 A/sec, _, the film formation rate was 3.9 A/SeC, and Example 3, and the speed was slow, and the efficiency of the money was not improved.
