Media

CAUTION: Do not degauss LTO cartridges! Ultrium LTO cartridges are pre-recorded with a magnetic servo signal at the factory. This signal is required in order to use the cartridge with the Ultrium LTO drive. Keep magnetically charged objects out of close range.

Regarding media, observe these general rules:

Use only LTO Ultrium1 formatted cartridges. Ultrium formatted cartridges contain embedded servo code, written on the media, during the cartridge manufacturing process. LTO Ultrium1 cartridges cannot be bulk erased or degaussed.
Clean the tape drive when the Clean Drive LED is illuminated. Be sure to use only LTO Ultrium universal cleaning cartridges.

Table 5 provides the media requirements necessary to use the LTO Ultrium tape drive.
