Overland Data, Inc., the market leader in mid-range tape automation solutions, today announced that Quantum Corporation, a leading provider of data protection and network storage, has signed an agreement to license Overland's patented Variable Rate Randomizer (VR2™) technology. Overland's VR2 technology will be integrated into future Quantum tape drive offerings.

Today, the installed base of Quantum DLTtape drives is more than 1.7 million. Additionally, tens of thousands of the new Super DLTtape drives have been shipped to date. The first of the next generation of Super DLTtape drives is the SDLT 220 drive which operates at a native capacity of 110 GB and a native transfer rate of 11MB/second. Quantum’s published technology development roadmap takes Super DLTtape technology to a native capacity of 1.2 terabytes (2.4 terabytes compressed) on a single cartridge, with a transfer rate of over 100 MB/s (megabytes per second).

Overland's VR2 substantially increases the capacity and throughput of linear tape formats. The first successful implementation of Partial Response Maximum Likelihood (PRML) channel encoding technology on linear tape drive platforms, VR2 can increase native capacity and native data transfer rate performance of existing linear tape technologies by as much as 50 to 100 percent without requiring any changes in tape path design, recording heads and/or media. This is accomplished by achieving rate efficiency of greater than 99 percent, making it one of the most effective PRML implementations ever developed.

“IT customers are looking for data protection solutions that can help them keep up with the explosion of data on their network,” said Duncan Furness, vice president Quantum’s DLTtape Group. “Overland’s VR2 technology will help us deliver on customer needs for greater capacity and performance while helping DLTtape to remain the standard of choice for reliable tape solutions well into the future.”

Christopher Calisi, president and CEO of Overland, said, “The majority of our tape automation business is based upon DLT, and we are pleased that VR2 will be an enabling technology to advance the future success of DLTtape drives. Quantum now joins a growing roster of companies who have licensed VR2 including StorageTek, Seagate, Imation and Tandberg Data. We are optimistic that VR2 licensing revenue will make a meaningful contribution to Overland’s profitability beginning in calendar 2002.”
