The Application of High Density Tape Recording to Image Processing

Abstract

The Image Processing Facility at Goddard Space Flight Center has the requirement to move volumes of digital data (10¹¹ data bits per day) that exceed the capacity of conventional computer tape. This paper presents the requirements for a high density digital tape recorder compatible with conventional computer systems. The steps leading to the formulation of these requirements are described. The use and interaction of the recorder with the various elements in the facility are treated. The formulation of the requirements resulted in the selection of a Honeywell Model 96 Wideband II tape transport modified by Martin Marietta Corporation for digital serial-in, serial-out operation. This selection followed a competitive procurement action.
