Ten years ago IBM announced the 305 and 650 RAMAC Data Processing Systems---systems that heralded the on-line processing concept, wherein business transactions could be economically processed as they occurred. This was made possible largely through the use of the 350/355 Disk Storage Files, whose 5 million stored characters were directly accessible. Since that time, significant advancements have been made in direct-access memory development. These include the double density 350/355, the 1405, the 1301 and the 2302. Pioneering the removability and interchangeability features of direct-access storage media was the 1311 Disk Storage Drive. A further advancement is the 2321 Data Cell Drive.
