"The combination of these advances brought about a second generation of computers in 1960 with the delivery of the 1401 system. This second computer generation -- with its vast improvements in processing speed and capacity -- made extensive use of tape input/output systems, especially for record-keeping jobs. Year-to-date records on tape could be read into or out of computers at the previously unheard rate of forty-one thousand (41,000) characters per second. Besides speed of access, tape could store an enormous amount of information for its size in comparison with punched cards. A standard reel holds twenty-four hundred (2,400) feet of one-half inch wide tape and can contain data equivalent to about four hundred thousand (400,000) fully punched cards or two hundred (200) card boxes filled with punched cards."
