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. [3]

Memorex shipped the first HDD, the Memorex 630, in 1968, plug compatible to an IBM model 2311 marking the beginning of independent competition (Plug Compatible Manufacturers or PCMs) for HDDs attached to IBM systems.

Deskstar was the name of a product line of computer hard disk drives. It was originally announced by IBM in October 1994. [1] . The line was continued by Hitachi, when in 2003 it bought IBM's hard disk drive division and renamed it Hitachi Global Storage Technologies.

This matrix contains alerts, news, and documentation for the Hard Disk Drive (HDD) and Solid State Drive (SSD) firmware for various HDD / SSD vendors and the Data ONTAP® Disk Qualification Package (DQP) used with the IBM® System Storage™ N series storage systems.

The IBM3340 hard disk drive (HDD) that began shipping in November 1973 pioneered new low-cost, low-load, landing read/write heads with lubricated disks, and established what became the dominant HDD technology.

Dec 26, 2011 · In September 1956, IBM launched the 305 RAMAC (Random Access Method of Accounting and Control), the first commercial computer that used a moving-head hard disk drive (as opposed to sequential access magnetic tape storage).

In 1991, head and disk improvements in the IBM Corsair HDD raised the number to 132 Mbits/sq. inch. Corsair heads and disks were slightly improved versions of Sawmill components. In 1994, Fujitsu, Hitachi, and Hewlett Packard independently developed MR heads.
