DVD Tranfer rate

I posting cause I want some get a answers on this question.

[bold]DO[/bold] DVD have a faster tranfer rate then CD because:
-The laser lens is smaller
-DVD: 780 nanometers
-CD: 640 nanometers
The Pits and lands are smaller
-DVD: -740 nanometers separate one track from the next
-elongated bumps that make up the track are each 320 nanometers wide.
-a minimum of 400 nanometers long and 120 nanometers high, the demenstions of a "bumps"

Do all these account for the faster data transfer rate for the DVD player compared to the CD player. If not then what elese am I missing.
