PURPOSE:To ensure an uneven recording of information in a simple way, by recording the information on a electrostatic recording medium with an injection of the electrostatic charge and then sticking and hardening the foggy high molecular material solution on the information and in the electromagnetic field. CONSTITUTION:The metallic film 3 such as aluminum or the like is evaporated on the substrate 2 of mylar or the like, and then an insulated film of mylar or the like is coated on the film 3 as a recording layer. Thus a disk 1 is obtained. The record signal Vi superimposed by the DC high voltage EB is applied between the films 3 and 4 via the recording stylus 5, and then the information is recorded in the form of an injection of electrostatic charge. As a result, the electrostatic record pattern 6 is formed according to the signal Vi. Then the disk 1 is provided between the electrodes 8 and 9 to which the DC high voltage E is applied with sticking and hardening of the lacquer 7 under an electrostatic field condition. Thus an uneven pattern 10 is formed. In such way, an uneven recording is possible in a simple process. |
