Log of cost per bit of storage technologies is plotted versus year first installed in a product. Least expensive are magnetic tapes stored on a shelf, followed by magnetic disk packs stored on a shelf. When loaded on tape or , these technologies have about the same cost per bit, but disks generally provide more rapid access to data. Fixed-head files (FHF) are magnetic drum memories with one read-write head for each track. refers to ferrite- memory. FETs are field-effect , and BIPOLARS are bipolar with higher performance than FETS. The author first presented this figure at an AIP Conference in 1971; see References of Historical Significance in the Bibliography.
