Described are embodiments of an invention for storing write environment conditions of a tape cartridge. A tape drive measures and stores the write environment conditions for a portion of tape as a result of receiving a write command to write data to the same portion of tape. In one embodiment, the write environment conditions are measured and stored to the tape cartridge each time a write command is received such that each portion of tape written has corresponding stored write environment conditions. The write environment conditions include temperature and relative humidity in one embodiment. The stored write environment conditions for each portion of tape written creates a historical log of the environment conditions that the tape was written within. The historical log can provide information to a manufacturer or user regarding the environmental conditions the user operates their tape drive within and provides information to assist with failure analysis.
