PRINCO, WHITE TOP DVD-R, 4X, 10PK JEWEL CASE

 Only 1 coaster per 100. Works with Sony DRU-810A
I have been using these discs for years, and have found a few things:

Advantages:
- The all white top makes it much nicer to write on: no annoying product information to have to write around.
- Has worked in my Sony DRU-530A and DRU-810A burners. (Even though Sony does not recognize them on their compatibility list.)
- During some burns, I have been able to push it beyond 4x. Not often, though.

Annoyances:
- SOME markers tend to blur/bleed out while writing on the top (white) surface. (i.e. the green Sharpie, but not the red. Weird.)
- I have noticed in my last 50-pack that I had three discs that had defective surfaces. One had a bubble near the outer edge that could not be written over, and the other two had very small blank/voided spots near the outer edge - it looked like the writing surface wasn't even there. They became coasters only because I had to write to the very edge; otherwise they would have been useful.

If you are buying these for the first time, you may want to try it out before buying a 50-pack. My first spindle was given to me by someone that couldn't use them in his burner. NOT ALL BLANK MEDIA WORKS IN ALL BURNERS! IF IT DOES BURN, IT IS NOT A GUARANTEE THAT IT WILL WORK IN YOUR OTHER DVD PLAYERS! This goes for most blank media on the market.

I originally bought a 100-pack of Memorex DVD-R -- thinking it's a name-brand and I can't go wrong -- but not only did 50% of the discs fail to burn, but the ones that did burn correctly failed to play in most of my DVD Players. I have not experienced this with the Princo discs.

I HIGHLY recommend this to owners of Sony DVD burners. Owners of other burners... try it out.
