The IBM 2321 Data Cell Drive (2010) (archive.org) 20 points by segfaultbuserr 31 days ago | hide | past | favorite | 2 comments. 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. A further advancement is the 2321 Data Cell Drive. 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. The IBM 2321 Data Cell announced in April 1964 (withdrawn January 1975) is a direct access storage device for the IBM System/360.

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).

When the 2321 data cell was discontinued in January 1975, the addressing scheme and the device itself was referred to as CHR or CTR for cylinder-track-record, as the bin number was always 0. IBM refers to the data records programmers work with as logical records, and the … IBM 2321 Data Cell: | | ||| | IBM 2321 Data Cell at the University of Michigan Compu World Heritage Encyclopedia, the aggregation of the largest online encyclopedias available, and the most definitive collection ever assembled.
