Who makes UJ-857D?
 

I have some TDK double-layer DVD+R's. The ID returned by my MacBook and by the program DVD Media Inspector is UJ-857D. I don't see that listed on the page http://www.digitalfaq.com/reviews/dvd-media.htm. Does anyone know who the manufacturer is and what the quality is? Thanks.

OK, I see from further browsing that UJ-857D is the ID of my burner, not the media itself. But the page http://www.digitalfaq.com/reviews/dvd-media.htm seems to suggest that the program DVD Media Inspector is supposed to return the ID of the media, and the *only* thing it returns is UJ-857D.

Actually, you're reading the drive model. Your Apple, like many others, has a Matshita DVD-R UJ-857D burner inside. That's not the disc ID.

Look for something along the lines of TDKG or CMC or CMCMAG followed by other letters/numbers. That's the media ID.

Easy mistake. :)

Ah! You beat me to it.
You can also look for the media ID inside of most versions of Toast.

Unfortunately, I'm Mac-less these days, so I can't take a screen shot of exactly what you need to look for. (Know anybody that has one cheap, or wants to make a donation to our cause?)

It was recently mentioned on another site that...
Maybe that will help, too! :)

Thanks for the reply. I discovered that the way to use the program is to highlight the drive name and ID number. Unfortunately, *still* nothing showed up, except a message to the effect that some drives are not able to read the media ID information. (Which, no doubt, is why nothing except "DVD+R DL" showed up in System Profiler either.)
