In the early days of electronic data processing, new application requirements arose that could not be met adequately by batch processing, a mode dictated by the sequential nature of card and tape input-output equipment. Users needed a device to store and directly access relatively large amounts of data on-line. The first such products, IBM's RAMAC disk file and Sperry Rand's Randex drum, partially answered these needs. However, their use could be justified only for storage of highly active data due to their limited capacity and high cost compared to off-line tape storage.
