Exhibit 99.1

QUANTUM AND STORAGETEK ENTER INTO PATENT CROSS LICENSE AGREEMENT AND SETTLE ALL LEGAL CLAIMS REGARDING PATENT INFRINGEMENT LITIGATION

SAN JOSE, Calif., Feb. 28, 2006 – Quantum Corp. (NYSE:DSS), a global leader in storage, today announced that the company and StorageTek, a wholly-owned subsidiary of Sun Microsystems, Inc. (NASDAQ:SUNW), have entered into a patent cross license agreement and settled all legal claims related to a legacy patent infringement lawsuit StorageTek filed against Quantum before Sun acquired StorageTek in August 2005. The April 2003 lawsuit related to the use of an optical servo system in Quantum’s SDLT™ tape drives. Under the cross license agreement, Quantum and StorageTek will have license to a limited number of the other’s patents on a nonexclusive, worldwide basis. In addition, as a result of the cross license agreement, Sun has dismissed the StorageTek lawsuit against Quantum, and Quantum has agreed to pay Sun a total of $25 million – $20 million in the current quarter and the remaining $5 million over the next five quarters.

“The patent cross license agreement demonstrates the commitment of Quantum and Sun/StorageTek to building a stronger business partnership centered on meeting customers’ storage and data protection needs,” said Rick Belluzzo, chairman and CEO of Quantum. “The agreement and the related legal settlement serve the best interests of Quantum and our shareholders by putting the legal dispute behind us and enabling the two companies to focus all our interactions on enhancing this partnership. Quantum agreed to settle after considering the benefits of the cross license agreement, the additional legal costs we would have incurred in proceeding with the trial, the uncertainty inherent in any jury case and the potential impact on our business if we lost in court.”

Impact on Quantum’s Fiscal Fourth Quarter Earnings

As a result of this settlement with Sun, Quantum announced that its GAAP earnings for the current, fiscal fourth quarter of 2006 could be negatively impacted by up to $25 million. Quantum also said that it is undertaking a valuation process to determine the potential future financial benefit related to the cross license agreement and that it expects this valuation process to be concluded by the end of March.

Additional Information Regarding StorageTek’s Lawsuit Against Quantum

On April 15, 2003, StorageTek sued Quantum, alleging that Quantum had engaged in the unlawful manufacture and sale of SDLT tape drives and media products that infringed on two StorageTek patents. The StorageTek lawsuit sought a permanent injunction against the sale of these Quantum products and monetary damages of $142 million, including treble damages for alleged willful violations of StorageTek’s patents. The lawsuit was scheduled to be tried in the U.S. Federal District Court in Denver beginning on February 27, 2006, but was withdrawn as a result of the settlement between Quantum and Sun.
