I know that vcr tapes wear out from playing them. I was originally
told that dvds never wear out but now I hear different. One thing I
dont understand is that when a dvd is burned, a laser melts the data
on to the dvd. Then that same laser plays the dvd later. It only
makes sense that each time a dvd is played the laser melts more of the
disk, so eventually the dvd wears out or should I say the data melts
away. This got me asking how many times a dvd can be played before it
dies? I heard that dvds made at home die much sooner than the
commercial ones because the commercial ones are made more durable. Is
this true?
