Data cartridges, like all magnetic media, require periodic cleaning
and retensioning to remove surface debris and dirt that interferes
with proper head/tape contact. The 3491e automatic cleaner thoroughly
cleans and retensions all IBM and compatible half-inch data cartridges
which conform to IBM publication GA 32-0048 (3480, 3490 & 3490e).
The machine uses a vacuum-assisted gemstone-cleaning
blade to remove contamination from the oxide surface of the tape.
Each blade is good for 2,000 passes. The machine automatically indicates
when the blade requires changing.
Two cleaning tissues are used to remove contamination
from both sides of the tape, and the machine automatically indicates
when the tissue cartridges require changing.
The machine drive design incorporates hydrostatic
air bearings to minimize tape contact and friction. It uses microprocessor
controlled tension transducers to provide accurate winding and tensioning.
Air filters and ionizers are included to purify the environment
and eliminate static. The microprocessors automatically set tension
per ANSI standards for each type of cartridge.
Autoloader - Ten Cartridge Magazine
The 3491e is fast enough to clean ten (10) tapes
unattended in less than half an hour. Cartridges are housed in a
removable ten-cartridge magazine that is placed in the loading mechanism
for processing. Each cartridge is then automatically positioned,
loaded, processed, and unloaded sequentially.
Optical Scanner (OPTION)
This optional feature provides detection and recording of any physical
tape imperfection. Wrinkles, edge stretches, oxide voids, shedding
oxide, or any anomaly on the oxide surface is detected. Defects
.0025 inches or larger are detected.
