Luminex and MDI Partner For Development of UDF Filesystem Products to Support Removeable Media Data Storage

Riverside, CA - November 30, 1998 - Luminex announced today a partnership with Micro Design International (MDI) for development of new products that support the Universal Disk Format (UDF) for removable media data storage. Luminex will license MDI's UDF file system and repair utility, known as UNISON, for its complete line of UNIX focused storage and archiving products.

UNISON technology was developed to promote the cross-platform compatibility of new rewritable media technologies such as DVD, magneto-optical, and TeraStor's NFR. Based on and compliant with the Optical Storage Technology Association's (OSTA) UDF specification, UNISON is file system technology capable of reading and writing to any removable rewritable storage medium as easily as you would a hard disk. The data is written according to an OSTA specification making it accessible on all popular platforms. Additionally, UDF file system repair is an integral part of UNISON technology.

UDF is a universal vendor-independent file system designed for data interchange and portability allowing an operating system to access (read/write/modify) data that was created by another operating system. It is a subset of an International Standards Organization (ISO) interchange standard for non-sequential recording of data, known as ISO 13346. In 1991, MDI played an active role in the development of the original writeable file system standard, known as NSR, and has since manufactured many software products based on the evolving file system standard.

Luminex is the leading UNIX focused developer of CD library based storage and archiving software. Luminex will incorporate MDI's UDF-based UNISON technology into a broad range of new products to be released in early 1999. "We are excited about working with MDI to bring this technology into our product line" says Arthur Tolsma, Director of Business Development at Luminex. "By leveraging the quality and success of MDI's UNISON technology, Luminex is able to continue focusing on customer requirements and bringing these products to market quickly."

The source license partnership between Luminex and MDI involves a significant amount of software development by both parties. Luminex will adapt the robust MDI UDF filesystem and file repair programs to a broad range of UNIX operating systems. Luminex will also incorporate these technologies into their leading Fire Series library management product line. By working with Luminex, MDI gains a UNIX focused software partner that will carry the MDI UNISON technology to every major brand of UNIX.

"Our partnership with Luminex provides a broader platform for adoption of UDF with their upcoming UNIX products. The customer will benefit greatly from the robust file interchange and data portability available across multiple platforms," according to Steve Hammond, Vice President of Sales and Marketing at MDI. "Luminex has a strong reputation of high quality products and experience in the UNIX storage marketplace. We are pleased they have elected to partner with us in promoting the UDF standard by incorporating our robust UNISON enterprise implementation into products designed for those markets."
