QUANTUM AND READ-RITE ANNOUNCE DEVELOPMENT AGREEMENT FOR SUPER DLTTAPE-BASED PRODUCTS

Read-Rite to develop and supply magnetoresistive multi-channel recording heads for Super DLTtape products

MILPITAS, CA -- October 14, 1998 -- Quantum Corporation (NMS: QNTM) and Read-Rite Corporation (NASDAQ: RDRT) today announced a development agreement through which Read-Rite Corporation will develop and supply magnetoresistive (MR) recording heads for Quantum's next generation tape-drive products, based on the Super DLTtape� technology. The MR heads will be used in the Super DLTtape Magneto Resistive Cluster, which can deliver higher data-transfer rates and capacity than traditional MR heads.

Read-Rite has been supplying leading storage companies with MR heads since 1994, and is considered to be a premier provider of this technology. The MR technology for Super DLTtape products is expected to leverage Read-Rite's established expertise in MR head development and manufacturing. This enables a breakthrough product not currently offered to other companies, as tape-head technology is taken to a new level of performance. Quantum and Read-Rite plan to work closely on the development of this new multi-generation head technology.

"We are pleased that Quantum has chosen Read-Rite for this strategic relationship," said Cyril J. Yansouni, chairman and chief executive officer of Read-Rite Corporation. "We have committed dedicated resources to the development and manufacturing of MR tape heads. This speaks to the high level of confidence that Read-Rite has in Quantum and in the promise of Super DLTtape technology."

"Read-Rite is a proven independent technology leader and we have a high degree of confidence in their development and manufacturing expertise as well as their understanding of our technology, quality standards and schedules," said George Saliba, Quantum vice president of advanced development and group chief technical officer. "This new venture with Read-Rite is evidence of the strong momentum of Super DLTtape technology development."

Quantum plans to source its key components for Super DLTtape-based products from multiple suppliers. Read-Rite is the first source identified by Quantum for MR heads for this program. As with its DLTtape products, Quantum will conduct final assembly of Super DLTtape products in its Colorado Springs facility.

About the Super DLTtape Technology

The Super DLTtape technology is Quantum's next-generation DLTtape technology. Expected to appear in products in mid-1999, Super DLTtape technology uses Laser Guided Magnetic Recording to deliver a fundamentally different approach to tape recording through a combination of optical and magnetic methods. Using four new technology breakthroughs, Super DLTtape can provide an order of magnitude increase in performance and capacity over current DLTtape products, while improving the cost-effectiveness and the modularity of the platform. DLTtape drives are the worldwide revenue leader among tape drives. The DLTtape platform has become the industry standard for protecting enterprise data stored on mid-range servers and is the pervasive backup and archival solution for large and mid-size businesses and organizations. The ubiquity of DLTtape drives stems from the fact that they are included in storage systems from every major computer-systems vendor-including Compaq Computer Corporation, Dell Computer Corporation, Hewlett-Packard Company, International Business Machines Corporation and Sun Microsystems, Inc.-and nearly every tape-automation vendor- including Advanced Digital Information Corporation, ATL Products, Inc., Breece Hill Technologies, Inc., Exabyte Corporation, Overland Data, Inc., Qualstar Corporation and Storage Technology Corporation. Comprehensive information about DLTtape technology is available on the http://www.dlttape.com web site.
