IBM 2321 DATA CELL DRIVE Alan F. Shugart and Yang-Hu Tong IBM Corporation, Systems Development Division San Jose, California INTRODUCTION 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.

IBM 2321 Data Cell. IBM 2321 Data Cell, 1964, held 400 MB of direct access storage on magnetic tape.

MagCards are a downscale from the 2321, which was, at its time the top end of random accessible online storage. They provide much larger storage than any punch card, and were introduced (1969) way before floppies in the early 1970s (*1). In the top panel, an IBM engineer holds a magnetic tape strip on which approximately 200,000 characters of information can be stored on an IBM 2321 Data Cell Drive. Two hundred such strips were contained in a data cell and 10 interchangeable cells could be mounted in the vertical drum seen in the drive (at right).

The total storage capacity was 400 million bytes or 800 million decimal digits. Up to eight 2321s could be attached to the IBM 2841 control unit, allowing an overall capacity of over 3GB. The IBM 2321 Data Cell Drive was a random access device that could store up to 400 million alphanumeric characters or up to 800 million decimal digits on magnetic strips mounted vertically around a rotating cylinder.

The IBM 2321 Data Cell Drive was introduced in 1964, after years of development work, as a very large capacity storage system. The total storage capacity was about 400 Mb. The drive accomodated 10 removable and interchangeable data cells like the one shown above. Each data cell contained 200 2.25" by 13" magnetic strips. IBM 2321 Data Cell Drive.
