Advanced Hand-Camera Design
The hand (or picker in the L20) is composed primarily of the reach carriage, reach belt,
reach motor, and the camera. The hand mounts to the Z carriage on the Z shaft. The
robot can exchange 200 cartridges per hour, so your job is completed faster.
The camera reads the volume serial numbers on the cartridge labels after you insert them
into the tape library. The library records cartridge numbers and location. In addition,
StorageTek's camera uses an innovative design, the Digital Vision Camera System, that
accommodates different media types.

Digital Vision Camera System

StorageTek's libraries use a patented Digital Vision Camera System for cartridge
management, adaptive targeting, and self-calibration. Self-calibration enables the library
to adapt to mechanical parameters that might change over time. This feature creates a
more robust, reliable library that will perform dependably over the long term.
Most automated libraries use a common laser bar-code scanner for reading labels on
cartridges. Common scanners—such as those used in grocery stores—do not provide the
advantages of StorageTek's Digital Vision Camera System, which can read marginal bar-
code labels. In addition, the Digital Vision Camera System detects empty cells while in
motion, reducing audit time.
