Understanding Barcodes
Each tape cartridge in the Scalar 1000 must have an external
label that is operator and machine readable to identify the
barcode number. A barcode uses only uppercase letters A-Z
and/or numeric values 0-9. The Scalar 1000 supports Code 39
and Storage Technology type barcode labels.
There are three media modes:
• EXTENDED - Labels may have 5 to 16 characters (media
identifiers and checksums have no special meaning)
• DEFAULT - Labels may have six characters, or six
characters plus one or two media identifier characters.
• MEDIA ID - Labels must have six characters and one or
two media identifier characters.
The ½-inch media identifier is a separate single character
barcode label that follows the six character label. All other
media identifiers are included with the six character VOLSER
on the same barcode label. See Table 6-1 on page 11.
Note
The six character AIT
barcode labels contain
a seventh character
checksum, which is
ignored in DEFAULT
media mode, is
reported as A in
MEDIA ID mode, and
interpreted as part of
the barcode in
EXTENDED mode.
