Hitachi GST (previously IBM Storage Technology Division) invented hard disk drives in 1957, the start of an evolution of storage products which are key to the information technology industry. Hitachi GST is a major innovator in disk drive technology and storage, and it is these technical innovations which maintain Hitachi's leadership in the storage industry.

Today, disk drives can be characterized by the mantra, "smaller form factors, faster, denser, cheaper: in an industry best described by fierce competition and rapid changes. But in the midst of this never-ending progress, one fact has remained constant: Hitachi GST's leadership technology.

The following pages describe the role Hitachi GST has played in the development of hard disk drive technology in the past decade as well as projected future direction. Much of the advanced technology that keeps Hitachi GST ahead of the competition originates from Hitachi's San Jose Research Center located in San Jose, California.
