Quantum Corporation

Quantum Corporation, was a manufacturer of tape drive products, based in San Jose, California. From its founding in 1980 until 2000, it was also a major disk storage manufacturer (usually #2 in market share behind Seagate), and was based in Milpitas, California. Quantum's first products were very popular; according to one of the company's historical documents, by 1982 it had a 25% share of the market.

By 2000, the hard drive market was getting squeezed. Personal computer sales were dropping, value drives had razor-thin margins and were only getting thinner, and several makers (notably Western Digital) were in trouble. Quantum decided to sell its hard drive division to Maxtor at this time. Maxtor continued most of Quantum's disk storage products and brands until it was announced in December 2005 that Seagate was buying Maxtor.
