BD-R for Data only?

[Ghitulescu]

It happened last week, when I picked a pack of these BD-Rs:
http://catalog2.panasonic.com/webapp/wcs/stores/images/LargerPhoto/LM-BR25DE_500.jpg
and I burned the same image I used to burn for testing purposes on a BD-RE. The BD-RE disk works in every BD-player (I haven't tested the Sharp), while the BD-R did not play, except in the Panasonic brands and the latest models of Samsung (because the older ones were not available :) at the time of testing).

AFAIK there's no difference in BD-R for Data vs. BD-R for Video. Or is it one?

PS: The BD-Re was burned using an LG BH10, the BD-R with a LiteOn 112.

Perhaps, as is supposedly the case with DVD media, the rewritable format has higher reflectivity and is, therefore, more readable...

[Ghitulescu]

The disk was recognised as BDR, yet not playable.
Besides, some of the Sonies have Panasonic-made drives inside, at least the earlier models, ...

Your latest post does not seem (to me) to be in any way related to what I posted.

Perhaps another member can provide further insight...

The disk was readable, and the standalones identified it as BDR. Should it not be readable, then it would have been indicated as Bad disk, No disk, Disk error and the like.

Hi Ghitulescu how are you doing,

This is an interesting thing you have found.

I have only used Traxdata -R 4 X disks (which I burn at X2). I dont think they state Video or data but as you say what would be the difference.

Has there been a stelth update to players so as to have certain BD-R disks (imprinted as data only) i.e. NO VIDEO ALLOWED. Perhaps paranoid on my part.

Logic would say that would not be comercial good sense I would have thought.

BUT so interesting. What do you think it is.

I did notice that the disks you have pic of is 1-2 x , I have not seen these disks but is the read rate fast enough for an average BD HD video rate. Could that be the problem. I would have thought it would just stutter in playback if that were the case.

Would be interested in what you find.

The BD-REs are 2x too. And I have to assume that 1x should be enough for BD-Video, exactly as 1x is for CD-DA and 1x is for DVD-Video. :)
I'll wait for my new HDD to test another BD-R, this time in the LG. The reason for burning the second disk in the LiteOn was to test it (brand new with return right if it doesn't work).

In Germany the BD-R/Es are extremely expensive, it's cheaper to buy a second original than a BD-R/E, especially when it's DL (50GB)*. So I don't wanna waste them for nothing. That was the background of the question.

I've searched the net for reports or any other info concerning the BD for Data but found nothing. These disks appear to be designed for industrial use (whatever it might be), maybe there's a mark on them as it is with CD-R vs. CD-R-Audio.

*I know there are also cheaper disks, but as most tests already shown, they're not reliable.

I have used the Traxdata disks from Amazon.co.uk, they are 25G 4X -R's which I burn at 2X. I have only had one failure which was my fault. The oldest disks are about 3 years, (I know thats not very long) and they have absolutley no problems.

They work out at about 1.15 UK Pounds each for a drum of 20. Nicely made disks as well.

I burned today another BDR of the same type, this time using the LG BH10. The disk was perfectly readable and playable.

Two conclusions:
1. it might have been a burning error, in the sense that something was not correctly burnt (due to incompatibilities between burner and medium)
2. the LG is more compatible than the LiteOn, at least with this brand.

As both the LG and LiteOn correctly burned BD-REs I exclude defective drives, defective data or data errors along the chain: laptop-USB-SATA-burner.

Workaround: to burn the Pannies with the LG only.

Hi Ghitulescu
Just out of interest, what software are you using to burn the disks and what are the ISO settings.
And please dont take any offence at these questions, I know that you know what you are doing.

[Ghitulescu]

I only use ImgBurn and I don't use ISO but UDF :) version 2.50. Maybe I'll try 2.60 next time, the standalones from Panasonic use 2.60.

Hi Ghitulescu

Yes I have always used UDF 2.50 for all BD stuff. Always works with pannys.
Seems that 2.50 is the recommended version for BD burnng.
Dont know about the later 2.60 version.
