Abstract
A bistable storage target for use with a cathode ray storage tube is provided with electrode members forming an interdigitated electrode means. Electrode members connected to one bus bar are provided with collector electrode means which extend through a storage dielectric covering the electrode means for collecting secondary electrons emitted from written areas of the storage dielectric. Electrode members connected to another bus bar are isolated from the first bus bar electrode members and they are raised to a predetermined positive voltage subsequent to the flood gun means being turned off, the writing gun is turned on and the electron beam is directed to a selected area of the target thereby erasing the stored written information thereon.
