2.2 General Description
Models accommodate one or four tape drives and have removable magazines for tape
cartridge storage. There are models that utilize AIT, LTO, SDLT and SAIT tape tech-
nology. All units operate on internationally available AC power. Brushless motors are
used exclusively. All digital closed-loop servo systems use magnetic and optical posi-
tion sensors. The servos automatically calibrate themselves, thus eliminating all elec-
trical adjustments. Preventive maintenance is reduced to replacing the Air Filter,
when so prompted by the control panel display and removing debris inside the RLS.
2.2.1 Motion Systems
• On the RLS-4124, 4221, 5116, 8116 and 8216H a rotating carousel is utilized
to hold four magazines containing tape cartridges. The carousel rotates in
90-degree increments to present one magazine (or 5 tape cartridge slots)
to the robotic handler. The carousel rotates in either direction to mini-
mize the access time to any data cartridge.
•
All other models utilize a patented storage array that holds 9 magazines in
a rectangular array that is 2 magazines wide and 5 magazines deep. One of
