Plextor Maximize Quality

Does anyone know what is maxmize quality function is used for in discjuggler.Benq,Matshita,Sony CD/DVD drives do not support this,only plextor drives have this support.

from the manual:
“This option will enable drive specific technologies, such as Audio Masterâ„¢, Audio Master HQâ„¢, VariRecâ„¢,
or VariRecâ„¢ II for high quality writing. By optimizing the laser power and using lower writing speeds, these
technologies vastly improve the quality of resulting discs. Changes in the writing speed will significantly
slow down the time to write a disc. This option will not appear for drives that do not feature these writing
…means DJ supports PX-716’s special features like VariRec.
