Hi!
That's not always true. Compared to a simple audio CD player, you're
right.
However, any computer CD-ROM drive, CD burner, or even a CD player
designed
to use digital audio extraction will spin as fast or much faster than a
DVD
playback drive.
Besides, doesn't moving more air across the pickup just result in more
stubborn dust appearing?

Hi William,
not in my experience. In many years of attending to DVD players - since they
first appeared, I don't think that I can ever remember seeing a dusty
pickup, like you often see on CD players, or any playability problems being
cured by cleaning a lens, which they of course often are on CD players. I
was originally told the ' wind under the disc ' explanation by a Toshiba TLO
on a training course he was giving, so believe it - or not, as the fancy
takes you. Always seemed like a reasonable proposition to me.
You are of course correct in that computer CD ROM drives spin the disc up at
very high speeds, but the fact that the drive is pretty much closed in means
that they don't really get dusty anyway, and like DVD drives, they never fix
by cleaning ...
None of this alters the fact that the OP's laser is still likely to be
faulty d;~}
