What brand and type CD recorder are you using?

I'll bet you don't know everything about all of them. You're just
putting off the inevitable answer, which is "ask the manufacturer."

For what it's worth, I have a TASCAM CD-RW5000 CD recorder that I used
to use as an A/D converter because it was the best one I had at the
time. It was on for several hours a day. On this one, when you put a
disk in, it does the laser power check and after about two minutes in
standby, it stops spinning (and I assume the laser turns off). There's
room for 99 "tests" on a disk and I just saved aside one disk for this
use. I guess I haven't done it 99 times because I never had to use a
second disk.

Hi, thanks for the replies.
Its a prosumer level unit...Phillips CDR560..
Yes, when you put the disc in, it does optical power calibration then
goes to standby. When you press record, it says wait, the disc spins
up and the level meters start to work and the audio passes through and
the counter stays at 0:00. It will stay that way indefintley till you
press go. I'm not worried about the spindle motor, that is designed
to run for many hours, I do worry about the laser running on high
power record mode. My guess is that the laser is not in high power
mode at this point because it would burn the disc and CD-R disc can
only burn once so this part of the dics would be ruined, my guess is
it is in low power playback mode so that it can track and be in the
right spot to be ready to record immediatly when I press run....but I
was wondering if anyone knew for sure.

Yes, I accidently left one turned on with a disc in it connected to a
switched outlet so that everytime I tunred the light on, it powered up
and went through the optical power calibration routine, when I
finally noticed it (well after 99 on/ off cycles) the OPC area of that
particualr disc was full.
