IBM manufactured magnetic disk storage devices from 1956 to 2003, when it sold its hard disk drive business to Hitachi. [1] [2] Both the hard disk drive (HDD) and floppy disk drive (FDD) were invented by IBM and as such IBM's employees were responsible for many of the innovations in these products and their technologies.

Kennedy Company, often shortened to Kennedy Co., was an American computer storage company active from 1963 to 1988.Founded by Charles J. Kennedy (1920–1996) and based in the Greater Los Angeles area, the company was one of the largest independent manufacturers of magnetic-tape data drives for mainframe and minicomputer users. [1]
Magnetic storage media, primarily hard disks, are widely used to store computer data as well as audio and video signals. In the field of computing, the term magnetic storage is preferred and in the field of audio and video production, the term magnetic recording is more commonly used. The distinction is less technical and more a matter of ...
Caelus Memories, Inc., was an American computer hardware company active from 1967 to 1985 and based in San Jose, California.The company focused on the manufacturing of magnetic data storage media, primarily disk packs.
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.
The recording employs various electronic, magnetic, optical, or mechanical changes to the disk's surface layer. A disk drive is a device implementing such a storage mechanism. Notable types are hard disk drives (HDD), containing one or more non-removable rigid platters ; the floppy disk drive (FDD) and its removable floppy disk ; and various ...
During the designing of the 6600, CDC had set up Project SPIN to supply the system with a high speed hard disk memory system. At the time it was unclear if disks would replace magnetic memory drums, or whether fixed or removable disks would become the more prevalent. SPIN explored all of these approaches, and eventually delivered a 28" diameter ...
Data storage is the recording (storing) of information in a storage medium. Handwriting, phonographic recording, magnetic tape, and optical discs are all examples of storage media.
