A direct access storage device which stored data on individual magnetic strips. These strips are contained in removable-interchangeable data cells. The IBM 2321 Data Cell Drive had 10 data cells with 20 subcells per cell; each subcell has 10 magnetic strips. Each data cell could contain 39.2 million bytes or 78.5 packed decimal digits. A single 2321 data cell drive could have had on-line access to a maximum of 392 million bytes or 784 million packed decimal digits and signs. |
