Seagate Technology PLC (commonly referred to as Seagate) is an American-founded data storage company. It was incorporated in 1978 as Shugart Technology. Since 2010, the company
is incorporated in Dublin, Ireland, with operational headquarters in Cupertino, California, United States.〔(【引用サイトリンク】 Working for Seagate in Cupertino, CA )〕
Seagate developed the first 5.25-inch hard disk drive (HDD), the 5-megabyte ST-506, in 1980. They were a major supplier in the microcomputer market during the 1980s, especially after the introduction of the IBM XT in 1983. Today Seagate along with Western Digital dominates the HDD market. Much of their growth has come through acquisition of competitors. In 1989, Seagate acquired Control Data Corporation's Imprimis division, makers of CDC's HDD products. Seagate acquired Conner Peripherals in 1996, Maxtor in 2006, and Samsung's HDD business in 2011.
==Founding as Shugart Technology==
Seagate Technology (then called Shugart Technology) was incorporated on November 1, 1978 and commenced operations with co-founders Al Shugart, Tom Mitchell, Doug Mahon, Finis Conner and Syed Iftikar in October 1979.〔Seagate Technology Prospectus, September 24, 1981, p.4〕 The company came into being when Conner approached Shugart with the idea of starting a new company to develop 5.25-inch HDDs which Conner predicted would be a coming economic boom in the disk drive market.〔 The name was changed to Seagate Technology to avoid a lawsuit from Xerox's subsidiary Shugart Associates (also founded by Shugart).
