The IBM 1301 Disk Storage Unit was announced in June 1961 and used with the 7000 series of IBM mainframes and with the IBM 1410 Data Processing System. As many as five 1301 units could be attached to a computer system to provide a maximum storage capacity of 280 million characters for the 7000 series and 250 million for the 1410.
