PURPOSE:To improve moisture resistance and long-term storage property by a simple constitution by sticking a first and a second substrate with an adhesive in which metal powder is dispersed. CONSTITUTION:The adhesive 3 is thermosetting resin or UV curing resin, into which one kind of metal powder 4 selected from Ti, Al, Mg, Bi, Ta, Si, W, Cl, Pd, etc., is almost homogeneously dispersed. The adhesive 3 is applied on the recording film of the substrate 1, to which a protective plate 5 is stuck to obtain the information medium disk 6. By using the adhesive 3 with metal powder 4 dispersed, oxygen contained in the water which intrudes into the adhesive reacts with the metal to produce oxides. Thereby, intrusion of oxygen into the recording film can be prevented. Thus, oxidation deterioration of the recording medium layer can be prevented and long-term storage property of the medium can be improved. |
