Overland Doubles Tape Capacity

Storage vendor Overland Data Inc. announced a new tape drive with double the storage capacity for enterprise networks and service providers.

The AIT LibraryPro is a modular, rack-mountable tape library that uses Sony Corp.'s AIT-3 tape drive technology to offer up to 47 terabytes of storage capacity, more than twice that of previous tape drives. It also can back up data at up to 1.85 terabytes per hour.

Sony's AIT-3 tape technology was introduced in May 1999 and claimed to be able to store one billion bytes of data on one square inch of tape. The gain in capacity is achieved by switching from conventional inductive recording to magneto-resistive heads. Magneto-resistive heads provide a higher signal-to-noise ratio than inductive heads. AIT-3 technology is read/write compatible with AIT-1 and AIT-2 media.

Each LibraryPro can contain hold nine modules. Each module consists of 20 tape cartridges, and each cartridge holds up to 260 G-bytes of compressed data.

The LibraryPro with new AIT-3 tape drives will be available in mid-2001. Pricing is not available.www.overlanddata.com
