Exceptional Reliability
Advanced design minimizes the number of moving parts and electronic connectors for unparalleled reliability with greater than 20,000-hour Mean Time Between Failure (MTBF).

Advanced Design Features
The compact, low-profile, 3˝ inch height integrates easily into most office environments. The unprecedented low weight is just 30 pounds. On-board cache memory is 1 MB. Autoload features assures easy operation and Advanced Tape Transport System (ATTS) extends tape life. Self-test diagnostics on power-up, low power usage of only 45 watts average, and autoranging power supply that runs on any standard line voltage in the world are more welcome advanced features. Tape reels from 7 to 10˝ inch are accommodated.

Efficient Operation
The design is power-efficient as well, drawing an average of just 45 watts. Equally efficient reel motors run cool and quiet. You’ll hardly notice the drive is on. No drive treats your tapes better than UNY-9T. Our Advanced Tape Transport System (ATTS) puts a microprocessor in charge of tape motion, eliminating mechanical parts which can add wear to your tapes and are more prone to fail. The microprocessor automatically optimizes tape tension for the tape being used. Cool running motors and our innovative Glass-Filled Thermoset (GFT) deckplate guard your tape from any heat. The enclosed tape path is kept virtually dust-free too.

Advanced Features
The 9T-SE and 9T-DF models in bring you true SCSI-2 compatibility in a sleek, 3˝ inch-high case. The UNY-9T drive offers you all the advanced benefits and features that have made the UNY-9T series the favorite of the industry. The most obvious benefits are UNY-9T’s small size and weight. The drive fits comfortably on the desktop, its sleek styling complementing any office. Or, mount it in a standard rack. If you need to move the drive, you’ll appreciate its low weight of just 30 pounds.

High-Performance Quad-Density UNY-7000T 9-Track Tape System

data interchange, 9 track

The UNY-7000T 9 Track Tape Drives are the ultimate high-performance 9-track tape drive operating in all four densities: 6250/3200/1600/800 bpi data formats.

The UNY-7000T 9 Track Tape Drives operates at 50 ips true start/stop and at 100 ips in streaming mode in all densities. Microprocessor-driven servos provide fast and reliable push button operation.

Two operating modes, programmable and auto-program are furnished. Via a front panel that includes LCD display, the operator may select start/stop or streaming, enable or disable cache buffers, adjust transfer rates and more. Auto-program permits the drive to select the mode of operation permitting the greatest overall throughput.

Available interfaces include the Pertec industry standard, SCSI, HPIB and RS-232.
