CDRom Power light

I have a BTCCDROM and the light on the cdrom remains lighted even when the CDROM is inactive.  When there is no cd in the drive it goes out but I believe this is the first cdrom drive that keeps the power light on when a cd is in but not in use.  Is this normal and if not...what causes it?

This is completely normal. I have a 12x Takaya, and it does exactly the same thing. I believe it has something to do with read ahead buffering.

I don't understand why it would have anything to do with read ahead buffering if the cd is not being asked to read anything.  For example, if I have a music cd in and it starts playing...then if I close down the cdplayer in windows...the playing stops...but the light remains on...are you suggesting that it keeps reading to maintain a buffer...but if this is so...why wouldn't it still stop reading once the buffer is full?

Is the cdrom spinning when the light is on? I have a cdrom where the light is on when the cd is inactive also. I assumed the light indicates a cd is in the drive, because it goes off when there is no cd.

I guess that must be it.  The cdroms I've encountered have all just had the light on when the cd rom was being accessed or when a disc is first inserted or ejected....not while just being in the cd and not being accessed.  But it does make sense just to let you know there is a cd in the drive.

Thanks for rejecting my answer, then giving the points to someone else that gave the same answer. You asked if it was normal, and I said yes.
