History of IBM magnetic disk drives
IBM manufactured magnetic disk storage devices from 1956 to 2003, when it sold its hard disk drive business to Hitachi. 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. The basic mechanical arrangement of hard disk drives has not changed since the IBM 1301. Disk drive performance and characteristics are measured by the same standards now as they were in the 1950s. Few products in history have enjoyed such spectacular declines in cost and size along with equally dramatic improvements in capacity and performance.
IBM manufactured 8-inch floppy disk drives from 1969 until the middle 1980s but was not a significant manufacturer of smaller sized floppy disk drives.〔1986 Disk/Trend Report — Flexible Disk Drives shows IBM production only of 8-inch FDDs and states, IBM will end internal production of 8-inch drives by 1987.〕 IBM always offered its magnetic disk drives for sale but did not offer them with original equipment manufacturer (OEM) terms and conditions until 1981.〔IBM Enters OEM Market For Winchester Disk Drives, Electronic News, September 14, 1981〕 By 1996 IBM had stopped making hard disk drives unique to its systems and was offering all its HDDs on an OEM basis.〔1996 Disk/Trend Report — Rigid Disk Drives, Specifications Section〕〔IBM's disk drive family has three new members, INFOWORLD, October 17, 1994, p.40〕
IBM has used many terms to describe its various magnetic disk drives, such as Direct Access Storage Device, Disk File and Diskette File; however, here the current industry standard terms, ''hard disk drive'' and ''floppy disk drive'' are used.
