An eraseable solid state optical memory has an array of selectively energizeable photoemitters which are imaged by suitable imaging means onto a data mask to optically address data stored thereon. To that end, the data mask is an eraseable optical recording medium, such as a tellurium suboxide or other chalcogenide material. A data writer is provided for programming, erasing and re-programming the data mask in situ while self-aligning the imaging means with the programmed data mask. The data mask may be erased and/or re-programmed in whole or part, thereby extending the utility of these memories to the storage of data that is subject to change.
