@ vbholaiit,

Perhaps the below How Stuff Works Web article will answer your question(s) ->

From reviewing your other CD Freaks posting of a couple a weeks ago perhaps if you re-visit that posting and provide the answer(s) to the questions other Forum Members asked you perhaps they can assist you with your underlying CD Burner problem.


PS – Using Google Search ( and/or WikiPedia ( will generally provide to answer to most of your questions.
