Tandon Corporation was a disk drive and PC manufacturer founded in 1975 (incorporated in 1976 as Tandon Magnetics Corp.) by Sirjang Lal Tandon, known as "Jugi" Tandon, a former mechanical engineer. The company originally produced magnetic recording read/write heads for the then-burgeoning floppy-drive market. Due to the labor-intensive nature of the product, production was carried out in India which was the key to the company's competitiveness. In the late 1970s, Tandon developed direct equivalents to Shugart floppy drives, and is credited with the invention of DS/DD (double-sided, double-density) versions which became its primary product in the early 1980s.
