Are these Sony DVD+R's good or simply 'ok'?

[DarkSniper]

Hi, I've recently acquired a spindle of 25 Sony "AccuCORE" DVD+R's with the intention of burning a full system backup to them. I've done some research on them, and I'm wondering if they're more likely to be the good Daxon discs, or the decent Lead Data discs. While the 2nd class Lead Data ones would be adequate for my purposes, I'd really like for them to be the 1st class Daxon ones.

Thanks in advanced

What I do know:
Disc ID: SONY/D21 [SONY-D21-00]
Country of Origin: Taiwan
Numbering Around Center Of Discs: DRP5GG0001 5L
UPC Code: 027242646476
P/N: 25DPR47RS4
Copyright Date On Packaging: 2008 [This leads me to think that they may be the 'good' Daxon discs, since they stopped making them in 2010]
They Do have a barcode opposite of the numbering in the center

Do they have any hub code?

[DarkSniper]

They don’t seem to, though it does say “DVD+R Ver. 1.3/1x-16x” in that area, if that’s of any meaning.

Also, slightly off-topic, but I’ve heard that sharpies are bad for DVD’s, but if you can fit your label on just the clear plastic in the center, then it’s ok. Is this true, or is it still bad for the discs?

On a [B]DVD[/B], however, you could write with a sharpie or even carve a label with a screwdriver, and it still wouldn’t harm the data in the middle of the disc - well protected 0,6 mm below the top surface.

Oh, I see! Holding a CD and a DVD up side by side makes it really easy to see that extra layer of plastic that DVD’s have.

Thanks for the info and the welcome

Oh, and with the hub code, I think I found it. It seems that it’s molded into the plastic at the very center of the disk [and is very, tiny and hard to read]. That number is Y16VS1333B21[O/0]D[O/0]72[O/0]5
I put [O/0] since I’m not sure if those are zeroes or O’s

They were made by Lead Data.

Thanks for your help in identifying these =D

I figured they’d probably be the Lead Data ones, since the container looked way too new to possibly be from before 2010, but you never know, especially with a misleading date on the package xD

Though these should be fine for a secondary backup, and so far have performed far better than the CMCMAG discs that I have left on my other spindle.
