Maxtor Corporation was an American manufacturer of computer hard disk drives founded in 1982 and acquired by Seagate in 2006. As of December 2005, just prior to the acquisition, Maxtor was the world's third-largest manufacturer of hard disks. It now operates as a subsidiary of Seagate.

Maxtor targeted both the server and desktop market, concentrating on disk capacity more than disk speed for desktops.

Early financing

The Maxtor founders, James McCoy, Jack Swartz, and Raymond Niedzwiecki, began the search for funding in 1981. The founders are all ex-employees of IBM and graduated from the San Jose State School of Engineering. In early 1982, B.J. Cassin and Chuck Hazel (Bay Partners) provided the initial $3 million funding and the company officially began operations on July 1, 1982. It shipped its first product in February 1983 to Convergent Technology and immediately received an additional $5.5 million in its second round of funding. The company also began negotiations with the EDB (Economic Development Board) of Singapore for favorable terms before committing to Singapore as its offshore manufacturing location. The DBS (Development Bank of Singapore) agreed to provide financing to help grow the company in Singapore. In 1983, the company established a liaison and procurement office in Tokyo, headed by Tatsuya Yamamoto.

Maxtor's product architecture used eight disks; 15 surfaces recorded data and the final surface was where the servo track information was located. The company developed its own spindle motor which was fitted within the casting containing the disks. This was a major departure, the motor usually being mounted external to the disks. The first product was designed to provide 190 MB of storage, but delays in getting magnetic heads to the Maxtor design resulted in the company taking what was available and the first drives were shipped with a capacity of only 140 MB. The company received an additional round of financing of approximately $37 million in 1984 before going public in 1985, with Goldman Sachs as the prime underwriter.

MiniScribe acquisition

In 1990 Maxtor entered the mass market with its purchase of the assets (but not the liabilities) of bankrupt MiniScribe in Longmont, Colorado. The transition was a tough one, with the early products of this union (notably the 7120 3.5-inch 120 MB drive) having many quality and design problems. Later products managed to sell well despite the initial problems, and in 1996 the company completely redesigned its drive lines, introducing the Texas Instruments DSP-based DiamondMax series.
