    The IBM 1301 Disk Storage Unit, [11] announced in 1961, introduced the usage of heads having self-acting air bearings (self-flying heads) with one head per each surface of the disks. It was followed in 1963 by the IBM 1302, with 4 times the capacity. Also in 1961, Bryant Computer Products introduced its 4000 series disk drives.

    The Williams tube, or the Williams–Kilburn tube named after inventors Freddie Williams and Tom Kilburn, is an early form of computer memory. [1] [2] It was the first random-access digital storage device, and was used successfully in several early computers. [3] The Williams tube works by displaying a grid of dots on a cathode-ray tube (CRT).
