(54) MEDIA INFORMATION

The invention relates to computing and can be used to record and display information.

Known matrix relief devices containing two parallel dielectric plates, on the inner surface of one of which are located the column electrodes, and the other - the row electrodes, and deformable layers placed between the plates. When the corresponding voltages are applied to the row electrodes and column electrodes, the surface relief of the deformable layer 1 and 2 forms under the action of an electric field in the intersection electrodes.

The lack of these devices is low reliability due to the occurrence of a noise background on the surface of the deformable layer.

The closest to the proposed technical essence is a device containing a transparent dielectric plate with row electrodes, a dielectric plate with column electrodes and a dielectric base, on both sides of which there are transparent electrically conductive layers connected with a thickness of zero.

the potential and the coating are deformable layers, and the plates with the rows and columns electrodes are located on both sides at a distance of 20–30 µm from the surfaces of the deformable layers GZ3.

 The disadvantages of the known device are low reliability, associated with the need for accurate installation of the gap between the electrodes and the surface of the deformable layer, and the possibility of rasterushen open

10 electrodes.

The purpose of the invention is to increase the reliability of the information carrier.

The goal is achieved by the fact that in a storage medium containing two parallel transparent dielectric

20, the inner surface of the first transparent dielectric plate and row electrodes, and the second onto the inner surface of the second transparent dielectric plate and column electrodes, and the zero potential splint, a specularly reflective flexible conductive layer is inserted between the deformable layers and connected to the zero potential tire. The drawing shows the media. The device contains a transparent dielectric plate 1, covered with transparent electrodes of rows 2, onto which a deformable layer 3 is applied, on the second dielectric plate 4 electrodes of columns 5 are coated, covered with a deformable layer 6, between the deformable layers 3 and 6 there is a conducting reflective flexible layer 7 connected to the ground potential. To record information, the sweep voltage is applied to the electrode of the recorded row 2. At the same time, appropriate control voltages are applied to all the electrodes of the columns 5. A geometrically relief is formed on the surface of the flexible specularly reflecting layer, the depth of which depends on the amplitudes of the voltages on the rows and columns electrodes. Sending in succession a sweep signal to each row and control voltage to all columns get a record of the entire image. Reading information can be made using slot systems. Thus, the proposed device improves the reliability of the information carrier on deformable layers.
