optical beam path is preserved · The storage area for performing the method is characterized in that the storage area according to the invention consists of a cantilevered tensioned film which, if necessary, is connected to a thin, electrically conductive and white ground to avoid charging phenomena on the wire facing the electron beam Layer is covered »

The Spelchermeditaa expediently consists of an electrical system conductive base plate, onto which one is exposed by electron beams applied vapor layer that can be decomposed into volatile constituents, is, in turn, covered by a thin electrically conductive layer. 1st * Optionally, over the electric Conduct another thin layer that can be decomposed into volatile components by electron beams Hatsrials be arranged, over which again an electric conductive layer can be arranged · Z./ delete the electrically conductive layers becomes an electrical Voltage anßologt.

ger incident current is used. ■ To store analog values, sweokmäSigerwelee, an area in the storage film corresponding to the size of the stored values, is worked out by beam deflection of the electron probe in only one coordinate direction Use "The analog value is thereby determined from the" each of the Ablonkaeit, while the electron probe passes through the recess in the Speloher layer. Eer lilektroaenstrahl is useful for reading by electron-optical imaging of an old; The image of the diaphragm is greater than or equal to the maximum area of the storage opening in the spherical medium. The beam current passing proportionally through the area of the storage opening is then used as an analog signal. Since when reading the stored information, the querying of the storage is tied to the temporarily unchangeable coordinate position of the storage point, it is advantageous not to use the storage layer as a self-supporting film, but as a ski CHT combination aiii "perform a dimensionally stable plate.
