First disk drive for random-access storage of data, 1955
IBM engineers led by Reynold Johnson design the first disk drive for random-access storage of data, offering more surface area for magnetization and storage than earlier drums. The Model 305 Disk Storage unit, later called the Random Access Method of Accounting and Control, is released in 1956 with a stack of fifty 24-inch aluminum disks storing 5 million bytes of data.
