PURPOSE:To simplify the manufacturing process, by avoiding the necessity of thin dielectric substance film and conductive surface layer uniformly, through the constitution of the information recording medium for electrostatic reproducing unit by conductive resin. CONSTITUTION:First, the groove 2 of non-signal is pitched on the lacquer plate 11, Ag thin film is reduced and separated on it, Ni is electrodeposited by taking it as the electrode and the metal plate 12 is obtained by separating it from the plate 11. At the convex corresponding to the bottom of the groove 122 of the plate 12, photo resist 13 is coated. After selective exposure with electron beam depending on the picture information to be recorded, it is developed. Next, Ag thin film is formed on the surface of the plate 12, Ni is plated on the master. The mother 15 having the groove 14 on which the information peeled off from the master is recorded as geometorical shape changes and the stamper 16 are similarly obtained. Further, the base material 18 and the conductive resin material 19 are laminated, they are heated and pressed between the metal-made base stands 17 and 20 with the stamper 16, to form the information track of specified pattern on the resin material 19. |
