VXA-1 Tape Drive

VXA-1 Tape Drive

VXAª revolutionizes the tape storage industry by using technology similar to that already proven in the networking, Internet and rewriteable CD markets. VXA-1 sets a new standard for data restore and interchange while offering extraordinary tape drive performance.

Discrete Packet Formatª (DPF)

The enabling foundation of VXA technology is its revolutionary Discrete Packet Format.  DPF enables data to be written and read in packet form, providing users a data restore capability unprecedented in the storage industry. The packets are uniquely addressed and can be read in any sequence.

Variable Speed Operationª (VSO)

Conventional streaming drives must operate at a constant speed, and when the flow of data to or from the drive is interrupted, the tape must be stopped and repositioned.  This ÒbackhitchingÓ significantly accelerates media and head wear, which in turn adversely impacts data reliability and the life of the drive mechanism. In contrast, the VXA-1 drive adjusts tape motion to match the host transfer rate, eliminating “backhitching.”  This capability significantly enhances media and drive reliability while optimizing backup and restore job times.

OverScan Operationª (OSO)

OverScan Operation is a technique for reading data packets independent of track shape or geometry. By reading packets with multiple scans, VXA virtually guarantees data restore.  This also ensures media interchange Ñ data on any VXA tape can be read by any VXA drive.

VXA Tape Technology

VXA Tape technology is the most advanced tape drive architecture available. In order to take full advantage of VXA technology, you need equally advanced data storage media.
VXAtapeª utilizes Advanced Metal Evaporated (AME) technology, which was developed
specifically to deliver the durability, archival and capacity properties required for high
performance tape drives. The media is made by passing the substrate through a vacuum
chamber where 100% cobalt material is deposited directly onto it. This has two
significant advantages over conventional Metal Particle media: It offers an optimized
recording surface, and there is no use of chemical binders which tend to break down,
introducing debris and contaminants into the head/tape interface.

An extremely hard, protective Diamond Like Coating (DLC) is applied over the magnetic
layer to make the media even more durable. It resists oxidation and moisture, and does
not leave residue on heads or tape path components.

Increased durability and reduced tape wear mean your data will be there, readable from
any VXA-1 drive. And as your storage capacity needs grow, VXA has a solution Ñ VXAtape is
available in 24 and 66 GB capacities. With an archival life of more than 30 years, the ability
to withstand up to 20,000 passes and a limited lifetime warranty, VXAtape is truly an
outstanding choice in data storage media. Please visit to learn
