General

 The Imation 45853 Royal Guard cartridge is a direct replacement for the discontinued Imation Black Watch 3490E cartridges. The cartridge has a capacity of 810 MB and has bar-code label and initialization options. In all other aspects the Imation cartridge is the same as a standard Imation Royal Guard 3490E. The proprietary backcoating available in the 45853 tape media protects against damage from static charges and absorbs debris as well.
