secure.log strange entry every 20 secs

[ole]

Hi,

I get this entry 3 times every minute
com.apple.SecurityServer[xx]: Succeeded authorizing right system.burn by client /usr/sbin/diskutil for authorization created by /usr/sbin/diskutil.

I tried to find out what does it means but could not get it, only something about a noise and a optical drive problem but it is not my case. (the optical drive does not make any noise and does not have any disc inserted)

Got this error when someone is logged in, if no one is logged but the computer is on, the error does not appear.

Thanks you in advanced,
Leo

Do any of the logged-in users that experience that recurring log message have a "burn" folder set up anywhere?
