WORM Media Errors

The following conditions cause WORM media errors to occur:
v Information in the servo manufacturer's word (SMW) on the tape must match
v Inserting a WORM tape cartridge into a drive that is not compatible with

Cleaning Cartridge

A specially labeled IBM LTO Ultrium Cleaning Cartridge is supplied in your
shipment to clean the drives in your library. The drive itself determines when a
head needs to be cleaned and communicates this to the library.
When the cleaning is finished, the drive ejects the cartridge and the Picker takes
the cartridge and places it back in its designated cleaning slot.
To remove a cleaning cartridge from its designated cleaning slot, export it from the
library.
The IBM Cleaning Cartridges are valid for 50 uses. The cartridge's LTO-CM chip
tracks the number of times that the cartridge is used.

Cartridge Memory Chip (LTO-CM)

All generations of the IBM LTO Ultrium Data Cartridges include a Linear
Tape-Open Cartridge Memory (LTO-CM) chip (
Media," on page 8-1), that contains information about the cartridge and the tape
(such as the name of the manufacturer that created the tape), as well as statistical
information about the cartridge's use. The LTO-CM enhances the efficiency of the
cartridge. For example, the LTO-CM stores the end-of-data location which, when
the next time this cartridge is inserted and the Write command is issued, enables
the drive to quickly locate the next available recording area and begin recording.
The LTO-CM also aids in determining the reliability of the cartridge by storing
data about its age, how many times it has been loaded, and how many errors it
has accumulated. Whenever a tape cartridge is unloaded, the tape drive writes any
pertinent information to the cartridge memory. The storage capacity of the
LTO-CM is 4096 bytes.
