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.
Computer data storage or digital data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. [1]: 15–16 The central processing unit (CPU) of a computer is what manipulates data by performing computations.
Cloud storage is a model of computer data ... to have been invented by J. C. R. Licklider in the 1960s with his ... mitigated through encryption technology.
The earliest form of non-volatile computer storage was the magnetic drum, invented in 1932 [33] and used in the Ferranti Mark 1, the world's first commercially available general-purpose electronic computer. [34] IBM introduced the first hard disk drive in 1956, as a component of their 305 RAMAC computer system.
Electronic data storage requires electrical power to store and retrieve data. Data storage in a digital, machine-readable medium is sometimes called digital data. Computer data storage is one of the core functions of a general-purpose computer. Electronic documents can be stored in much less space than paper documents. [3]

Among the groups reporting to Shugart was the team that invented the floppy disk. Shugart joined Memorex in 1969 as Vice President of its Equipment Division and led the development of its 3660 (compatible with IBM 2314) and 3670 (compatible with IBM 3330) disk storage subsystems. His team also developed the Memorex 650, one of the first ...
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 ...
