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
