Business/Technology Editors

SHREWSBURY, Mass.--(BUSINESS WIRE)--Aug. 5, 2002

Advanced MicroSensors, Inc. (AMS), a growing supplier of magneto-resistive (MR) tape heads and Micro-Electro-Mechanical Systems (MEMS) related products, today announced that it has successfully completed qualification and is shipping MR tape heads to Quantum Corporation for use in its SDLT 320 tape drive. The SDLT 320 holds 320 GB of compressed data on a tape cartridge about half the size of a standard VHS tape, while it transfers data at speeds up to 32 MB/s compressed, giving customers the performance they need to deal with shrinking back up windows.

AMS, a developer and manufacturer of advanced thin-film components and its strategic partner, Lafe Technology Ltd., who provides post-wafer processing, assembly, and packaging, are collaborating to produce MR tape heads for data storage applications.

"AMS is a strategic supplier of tape heads for Quantum and consistent with their past performance, they are again helping Quantum to successfully extend a standard of technology innovation, with the newly launched SDLT 320 tape drive," said Curt Kane, Vice President - Supply Chain Management, Quantum. "With the support and technical expertise that we received from AMS, the SDLT 320 demonstrates the innovation that customers expect from Quantum to help them backup and archive their business-critical information safely and reliably."

"The SDLT 320 is the second Super DLTtape drive using AMS/Lafe's heads," said Dr. Gunther Baubock, VP of Engineering of Advanced MicroSensors. "AMS is proud to have a relationship with Quantum and share in the success of the SDLT 320, as it offers customers 60 percent greater capacity than alternative mid-range tape drives and the highest performance available."

"AMS is pleased to have our advanced thin-film component products associated with Quantum's technology leadership in DLTtape and Super DLTtape products." said Ken Martin, Director of Tape Head Programs of Advanced MicroSensors. "It is satisfying to know that AMS products work in concert, with Quantum's performance and quality standards."
