Delkin Archival Gold DVD-R with Scratch Armour

Postby protog on Fri Jul 27, 2007 9:38 am

Hello all

I am new on here so I hope I have posted in the correct manor!

I wonder if anyone can help me. The above media which I purchased 100 off seems to have small dots in the dye?

Has anyone seen this before and is it a problem? I am a professional photographer and use the DVD's for backups.

Thanks

Andy

I've seen that before. Usually its due to dust or some other junk being on the disc when you burn it.

Ineresting idea, but that photo was from a disk which had no visible dust on when I put it into the Burner. Maybe the dust inside the burner gets onto the disks when the drive spins up.

The only other thing to add is that some disks have those dots where the laser didn't burn, i.e. towards the outer edge on a half full (or empty) DVD.

Thanks

If there wasn't any dust in the exact shape of the dots you're seeing, the discs are more than likely defective and you should return them immediately. (Strangest thing I saw was somehow a hair got on-- and stayed on-- a blank CDR years ago and burned a lovely shadow onto the disc. ;) )

I doubt your drive is kicking up dust, unless it is REALLY dusty. It's probably a defective dye layer. What is the Media ID of these discs? (if you use a program like CD Speed or something it should show you)

Definitely not something I would use for any sort of professional use (or even personal, really!). Dump them and buy some Taiyo Yuden for professional use.

I would recommend Taiyo Yuden for regular level important stuff... but for Photos and high level important stuff, that you really want to archive, then you should go for Maxell BQ 8x DVD-Rs. Nothing in North America touches them in terms of stability and manufacturing quality. They may not be gold media, but trust me, they perform in the same ballpark as you would expect from a gold disc!
