LTO Barcode Element Specifications
For the official IBM barcode label specification, see http://www-
01.ibm.com/support/docview.wss?uid=ssg1S7000429. Unless otherwise
specified, tolerances are X.XXX ± 0.127 mm, X.XXX ± 0.762 mm.
 Minimum symbol height is 11.1 mm, measured to the inside of the
label’s edge.
 The wide-to-narrow ratio is 2.75.
 The narrow element width is 0.432 mm +0.03 mm or –0.076 mm.
 The nominal width of the wide spaces and bars is 1.188 mm.
 The inter-character gap is 0.432 mm +0.03/–0.076 mm.
 The minimum quiet zone at the beginning and end of a printed barcode
string is 4.32 mm (10 times the narrow element width).
 The total nominal barcode string length (including quiet zones) is
74.088 mm.
 The edge of the barcode is the edge of the printed area associated with
the bar. The edge roughness is the transition encountered as a
horizontal line is moved vertically from all black to all white. The edge
roughness maximum is 0.038 mm.
 Variation between all bars, white and black, must be less than ±0.0381 mm.
LTO Physical Label Specifications
 Label stock must fit within the label recess on the face of the cartridge
without curling up on the sides or ends (79 mm X 17 mm +0/–0.8).
 Minimum length sufficient for the quiet zones, start-stop, and data
characters (nominal 74.088 mm).
 Minimum width no less than 1.5 mm narrower than the cartridge label
recess width. Corners are cut with a 1.5 mm radius.
 Maximum label thickness, including the RFID tag, if present, together
with any associated layers and adhesives cannot exceed 0.40 mm.
 The label and adhesive must have an environmental performance to
match or exceed the environmental specifications of the cartridge to
which it is applied.
