Cleaning and Diagnostic Labels
Description
• As the name implies, cleaning cartridges clean the tape path and

read/write heads of the tape drives.
• Diagnostic cartridges are for service representatives to run read and write
tests on the tape drive. In general, these tapes are standard data
cartridges with a special diagnostic label.
Cleaning cartridge
label format
• First generation LTO cleaning cartridge labels also use the media ID type
that coincides with the drive type.
• SDLT and 9840/9940 cleaning labels do not include the drive type
identifier (“V”) as the fourth character. This identifier began with the LTO
cleaning cartridges and will continue on future tape technologies.

Cleaning and diagnostic cartridges require different labels to distinguish them
from data cartridges.
The first three alphanumeric characters in the label sequence determine the
type of cartridge being used.
[ CLNvnn ], where:

“ CLN ” is the cleaning cartridge identifier,

“ v ” is the drive type identifier, blank or a space, and

“ nn ” is a sequence of numbers (such as CLNU01 or CLN 02).
Notes:
[ DG{space}nnn ], where

“ DG {space}” is the diagnostic cartridge identifier, and

“ nnn ” is a sequence of numbers (such as DG 001, and DG 019).
Diagnostic cartridge labels also require the unique media ID type that coincides
with the drive type
