What does TM stand for?

Additional new design features include a steel chassis for more durability; a soft-load mechanism to reduce normal wear and tear; a VR2 data channel device that enables higher densities; a park feature to ensure track alignment if the write-operation is paused or interrupted; and a thermal monitor that activates a firmware throttle-down feature when drive temperatures reach pre-determined levels.

However, because currently available real-time thermal monitors are configured as engineering tools, true process control is resource intensive.
