Abstract: Data were stored in a holographic archive memory using an optically controlled transparency. The requirements which the transparency should satisfy for the use as an input original were determined. A liquid-crystal transparency used is described. A report is given of the characteristics of an image obtained using such a transparency and also of an image reconstructed from a hologram recorded with the aid of the transparency. Ways of improving the image quality are indicated.
