    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).

    The Birkbeck ARC, the first of three machines developed at Birkbeck, University of London by Andrew Booth and Kathleen Booth, officially came online on this date. The control was entirely electromechanical and the memory was based on a rotating magnetic drum. [72] This was the first rotating drum storage device in existence. [73] 1948 June 21

    The machine was not intended to be a practical computer but was instead designed as a testbed for the Williams tube, the first random-access digital storage device. [113] Invented by Freddie Williams and Tom Kilburn [114] [115] at the University of Manchester in 1946 and 1947, it was a cathode-ray tube that used an effect called secondary ...

    When the first microcomputers were being developed in the 1970s, the 8-inch floppy found a place on them as one of the few "high speed, mass storage" devices that were even remotely affordable to the target market (individuals and small businesses). The first microcomputer operating system, CP/M, originally shipped

    Many people built or assembled their own computers as per published designs. For example, many thousands of people built the Galaksija home computer later in the early 1980s. The Altair was influential. It came before Apple Computer, as well as Microsoft which produced and sold the Altair BASIC programming language interpreter, Microsoft's ...

    The first computer to use magnetic tape. EDVAC could have new programs loaded from the tape. Proposed by John von Neumann, it was installed at the Institute for Advance Study, Princeton University, Princeton, New Jersey, US. 1951: Australia CSIRAC used to play music – the first time a computer was used as a musical instrument. 1951: US

    Drum memory of a Polish ZAM-41 computer Drum memory from the BESK computer, Sweden's first binary computer, which made its debut in 1953. Drum memory was a magnetic data storage device invented by Gustav Tauschek in 1932 in Austria. [1] [2] Drums were widely used in the 1950s and into the 1960s as computer memory.
