MSL5000 and 6000 Series Tape Libraries User Guide

Introduction
30 HP StorageWorks MSL5000 and MSL6000 Series Tape Libraries User Guide
Robotics
MSL Series tape library robotics consist of a cartridge shuttle, motor hardware,
motor drives, and other support electronics (see Figure 5). The four-drive models
also contain a vertical axis mechanism that enables the robotics to travel between
the upper and lower tape cartridge magazines. These robotics are capable of
picking and placing tapes throughout a 180-degree arc that consists of the tape
drives, tape cartridge magazines, and an optional Pass-Through Mechanism
(PTM).
The cartridge shuttle assembly includes a mounted bar code reader for scanning
labeled tape cartridges installed in the magazines and tape drives.
Note: Both full bar code reader scan and physical scan are conducted each time the
library is initially powered up, or each time a tape magazine is accessed using normal
operational modes.
In four-drive models, the robotic-PTM interface is at the lower vertical axis PTM
elevator position only.
