Eject audio disc when finished burning

As a follow up to my previous post, using Applescript I'm selecting some audio files in the Finder, importing them into iTunes, then burning a CD in one pass. I've tried adding, using Automator, a shell script at the end to eject the tray using

do shell script "drutil tray eject"

but the problem is the action wants to happen before the CD is finished burning and iTunes returns a no cd present error. Can anyone suggests a method to let the first action finish or a check to make sure there is a cd with data present before attempting to eject?

Tried below. No luck.

There doesn't appear to be anything in iTunes dictionary related to the state of burning CDs, so there's no direct way to detect when it's finished.

It's been a while since I've burned a disk, but your best bet may be an indirect approach - does iTunes post a dialog/window showing the burn progress? If that's the case you could add a loop inside your initial script to detect when this window disappears - something like:

set doneBurning to false

repeat until doneBurning

if not (existswindow "Burning CD") then -- change the name to whatever is actually used

set doneBurning to true

end if

delay 5 -- wait a bit before checking again...

end repeat

It's crude, but it should work.

Thanks Camelot. It doesn't actually popup a burning window, but does it within the initial window with a dialog (see screenshot). I did notice that upon inserting a blank CD, nothing is mounted on the Desktop, but after the burn, the disc is mounted on the Desktop. Could the Finder be focused or checked in a loop until the disc is mounted, then ejected at that point?

Hi,

You can use the "drutil status" command to get the information, like this:

The bash script:

#### wait until the burning begins
until $(drutil status | grep -q "Media Is Busy");do
    sleep 5
done

#### now, wait until the CD is finished burning
while $(drutil status | grep -q "Media Is Busy");do
    sleep 5
done

drutil tray eject ### eject the CD
