Infosmart 4x DVD-R...yay or nay?

[Stormshadow]

Just picked up sample of this media...and it burned well with my Pioneer A06.
I'd like to get more seeing that they cost 35% less than Ritek (atleast where I'm from).

But I'm just concerned with their longevity/quality, seeing that I'll be using them for archival purposes.

Anyone have any experience with this media?

It seems the media I am testing now are the same ones you bought.

Not good at all with Lite-On LDW-411S (even firmware FS0B.)

It burned alright with Plextor PX-708A but I couldn't run the DVD-Video with my PC though I could copy one of the files back to HDD safely (the file is played without problem. (Obviously I made a wrong compilation with Nero.)

Here's the media information.

I have a feeling that these have a link to AN31 media (which sucks). since I found both types of media in the same spindle.....

For longevity I don't know.

But they do seem okay when written by pioneer drives.

I tested the media with Pioneer DVR-A05 yesterday. Playback was OK.

NEC ND-1300A couldn't write to InfoSM media at all at any speed (not even at 1x). I tried firmware versions 1.06, 1.07v2, and 1.08. (1.07v2 custom-released.)

Lite-On LDW-411S recognized them 1x capable so I didn't bother testing any further.

Check out Info Smart's website:

and they claim 50 years of data life for their product, if anyone wants to take it at face value. It is currently one of the two major DVD discs manufacturers in Hong Kong.

^^Thanks for the link...couldn't find their website before.

I think I'm going to grab some more of these, because they did burn well with my A06.

Thanks.
