Direct access photomemory
A. J. Critchlow · 1958
The Direct Access Photomemory resulted as a continuation of the International Business Machines Corporation (IBM) research interest in random access memories for data processing which began with the Random Access Memory Accounting Computer (RAMAC). It was realized that large-capacity random access memories allowed the use of entirely new methods and techniques to drastically shorten data processing while providing valuable new services to the user. The model described in the first part of this paper was a research attempt into a new storage medium having the necessary characteristics.
