Step 4 – Prepare and install cartridges
Four types of AIT data cartridges are available: SDX1-25C, SDX1-35C,
SDX2-36C and SDX2-50C. The SDX1-25C and SDX2-36C are 170
meters in length, while the SDX1-35C and SDX2-50C are 230 meters
in length and all use Sony’s Advanced-Metal Evaporated (AME) tape.
All cartridges employ MIC technology, which incorporates a Flash
memory IC inside the data cartridge, allowing the architecture to capture
various system and user-related statistics directly within the MIC
structure to enhance data reliability, error prediction and successful
performance.
AIT barcode labels (see following illustration) must conform to the
Industry Standard Code 39 (3 of 9 code). Labels which meet the
requirements of ANSI MH10.8M-1983 must be used. They must contain
four to six alphanumeric characters plus a modulus 43 check character
on an 0.40-inch by 2.175-inch label. The barcode and numerics should
be centered horizontally. The narrow elements should be 0.015 +/- 0.004
inches (0.38 0.10mm), and the wide elements 0.030 +/- 0.004 inches
(0.76 0.10 mm). There must be a minimum of 0.2 inches of white space
at each end of the label. Use of a higher density is not recommended. If
a human readable label is not required, the barcode may extend across
the entire width of the label. Failure to comply with this specification
may affect reliability.
