Optical disk : unstoppable laser?
There is this sentence which doesn't make much sense to me:

because once the laser is on, it cannot stop

Hug? When writing on a CD-R/RW, DVD-R/RW/ +R/+RW thingy, what does the laser, except switch on and off at a very high speed? 212.27.60.48 (talk) 04:15, 13 September 2008 (UTC)

Why didn't you corrected this? It was a small, simple change. —Preceding unsigned comment added by 193.164.157.81 (talk) 13:23, 2 June 2009 (UTC)
