Evolution of digital magnetic tape systems for use in military environments

Abstract

The development of the electronic data processor has far outstripped similar developments in peripheral devices that feed, store, and receive data from the central processor. This imbalance has resulted in overall systems whose capability, performance, and size is primarily limited by the peripheral or ancillary devices. While a factor in commercial applications, these short-comings are particularly serious for equipment that must operate in military environments, under the control of military personnel. The Army and Navy, and their suppliers, have learned through experience that commercial or semi-militarized equipment will not operate reliably, nor can it be readily maintained under these conditions. These problems, when coupled with the severe size and weight limitations placed on transportable equipment, provided the impetus for this development program.
