Product Description

ATL-Specified DLTtape Drives

The DLT7000 is an advanced half-inch tape device able to store up to 35

gigabytes of uncompressed data per cartridge. Utilizing a linear serpentine

recording mechanism, a single DLT7000 drive is able to stream data at native

speeds of up to 5 MB/second. With its built-in data compression, the

DLT7000 can store up to 70 GB per cartridge with a throughput of up to 10

MB/second.* In addition, the DLTtape drive utilizes an adaptive cache buffering system that adjusts

to the streaming rate of the host, maximizing data transfer speeds. Furthermore, the DLTtape tape

drive is extremely reliable, with an average head life of 500,000 tape passes. Because the DLTtape

drive was not originally designed with automation in mind, ATL specified a unique version to ensure

compatibility and reliability within a robotics environment. The DLTtape drives used in ATL libraries

have a reliability rating 300% higher than standard DLTtape drives.**

Advantages of the ATL-Specified DLTtape Drive

Automated Cleaning

Cleaning an ATL-specified DLTtape drive is a lights-out operation. When DLTtape drives experience

excessive read/write errors they signal they need cleaning. Using a dedicated RS-422 interface, the

ATL-specified DLTtape drive requests a cleaning from the robot. Without user intervention, IntelliGrip

replaces the data cartridge with a cleaning cartridge and performs the procedure, returning the data

cartridge when the cleaning is complete.

Controlled Tape Ejection Distance

The ATL-specified DLTtape drive assures IntelliGrip can successfully pick a DLTtape cartridge by

controlling the cartridge ejection distance. Without this feature, a robotic mechanism may need to

make multiple attempts to select the cartridge, reducing overall system performance. ATLÕs process

of controlling ejection significantly reduces leader fatigue -- a critical requirement for high-cycle

automation environments.

Modified Timing

To ensure complete rewinds and cartridge de-coupling, the timing of various drive operations are

modified to enhance automated cartridge loading and unloading.
