Taiyo Yuden 4x DVD-R is *BACK* !!!

[Gen-An]

It's not *all* discs that are affected. It seems to be a somewhat random occurance, so you might have lucked out in the past. Who knows though, it could be the speckles are the reason they're being sold as value line.

I'm betting the speckles are at least part of the reason. It seems some people have bought the 4x shiny silver discs and seen the same dye flaws so apparently it's not an issue with silkscreening or applying a printable surface.

I'm posting a picture (sorry for the intense crop, I wanted to show it close up but fit the attachment limit) and some scans of one of the 'bad' TYG01s... this one luckily started towards the end of the disc so it wasn't a big deal. The disc was not full (only about 3.5gb used)

The picture was HARD to get. I tried all sorts of things and got lucky on this one. Most of the pictures showed nothing, even when I was way up close, macro zoom on, etc. I could barely even see it unless I was under flourescent lights. It's a weird problem with the dye... It's the discolored line pointing almost exactly towards the 'Compact Disc' logo of the case I put it in for pictures.

Hopefully this works since I've never posted pictures before! (The photo is entirely unretouched except for the crop/resize... I didn't touch the gamma, etc.)

Justin42: I've seen similar defects in Ritek media.

Here are the scans of that disc. PIE is surprisingly good over the flaw, PIF is worse than I thought it'd be given how good PIE was.

It was burned in a Plextor 716UF at 4X (rated speed).

Avg Max Total
PIE 1.21 11 16281
PIF 0.07 9 7329

I've actually seen this occasionally in Maxell spindles of TYG01. Never in Fuji TYG01s, though.

I have about 200 of these TYG01's from Supermediastore and probably 50-75% of them have flaws like this. :/ I don't blame SMS but it seems like you get what you pay for with these 'value line' media.

For stuff I need better then Acro Circle, I use Maxell Plus Series media, which is very close to Premium Taiyo Yuden, just with a MUCH smaller chance of bad bonding.

About those Maxell Plus discs...Do you happen to have one handy? I'd be interested to know what hub serial numbering scheme they use.
