New! 9.4GB DVD-R Double Sided @ Meritline

[SergeantD]

Only $3.49 a disc?!?! Hell it's worth a try. I just added 4 to my order and I'll let you know how they work for me.

Does this mean that it will be possible to just rip all the files from a orignal DVD then burn them back onto this blank dvd-r and you will have an EXACT COPY of the original DVD?

Don't hold you breath guys...

There's only 1 manufacture of double sided DVD's (if they tell you otherwise, then their full of crap) and they suck big time...

9.4gb DVD-R from cd-recordable.com is the units I tired....

First, they're supposed to be grade-A discs, they're really only B+ so they only like to record at 1x speed...but I actually had 1 that did 2x !!! must have been a fluke.....

Then...you can't put a label on then, only write REAL SMALL in the center hub area....

and the biggest thing !!!

The media is cheap, so therefore, the color is a dark purple, and out of 15 DVD players I've tried it in, only 2 worked, where my Apple/Pioneer media worked in 14 of them...

If you have a good "do it all" DVD player, then go for it, but if you plan on letting others watch or use it, well then good luck..

They're also great for data backup, but again, 1x at 4.3gig sucks !!!!

Jason

P.S. The new "light silver" grade A- media that's hitting the shows now at $.99 a piece seems to work great !!!

I bought 4 and so far, DVD players love it !!!! Gonna buy more next month

It's 4.3 gigs a side.


Only one company makes dual sided DVD-R?

Pioneer sells double sided discs. Since they make their own single sided, I'd think they'd make their own double sided.

[Faustus]

leebo is correct, there are 2 so far... Pioneer and Cd-recordables.com. And a third perhaps being whereever these new one are coming from... I'm interested to see what you find out about them.

[Jason A]

Well guys...I don't know where you get info about Pioneer making double sided media....

http://www.pioneerelectronics.com/Pioneer/CDA/Industrial/IndustrialProductDetails/0,14...,21838,00.html

The link above shows all their media that's avail for recording on the DVD-R/RW drives and none of them are double sided....

also a search for Pioneer DS media comes up with nothing...

As far as I know, again, there is only 1 producer and everybody else takes it and puts their name on it....

The color is weird and most drives don't like it.

Believe me, if there was a "GOOD" DS solution, then I'd be on it like right now and copying stuff....

Good luck with it.

Where are you getting these for .99? Have you had any problems with them?

[Faustus]

I agree, where are the 99cent dvd-rs coming from? I'd like to test them.

flaystus, thanks for the link, and I now stand corrected on their DS media !!! there's 2 now !!! I can only imagine how expensive that must be given the current price on single sided Pioneer media (OUCH !!!) I'll stick to Apple at $25 for 5 which is really just re-baged Pioneer media...

As for you woundering about the $.99 media, I don't know where you guys are from, but here in California, we have these BIG computer shows that take up 2 exhibit halls in Pamona (its BIG !!!)

anyways, there were3 media companies selling these dvd-r General discs. Sketchy at that price, I picked up only 4 just to try, but as it turns out, they seem to work great in other players, I don't have the name of the company or website, but when I go next weekend, I'll send you guys all the info.

Now PhilipL........ first of all..I never mentioned reflectivity at all, you brought that up !!!! Media that has a higher reflectivity rate has ALWAYS and will ALWAYS seem to have better compatibility in players be it cd-r,cd-rw,dvd-e etc... etc...

The common syndrome of using a HQ media for some reason has always held ture....sure there are different grades, but why this for example....

As in DVD-R, the Pioneer/Apple media is the highest compatible media out there, promising almost 90% of all DVD players will read it...

but how come other "Grade A/A+" media like TDX and Maxell DVD-R media which is a different color, will play in only 65%+ of all dvd players out there??? It has to do with the laser's ability to sense the recorded light&dark areas on the disc...

As for black media, well...it's really not black, only to our eyes it appears as such (if it was really BLACK, then how could any wavelength see through it??).....it's really a dark green color tint added to the polycarbonate layer, but allows the reddish/orangish 650nm wavelength to pass through....

Don't even start talking about it's not about the color.....look at these forums, look at the DVD player compat list to the left of here, look at what the 1000's of users find out...and report to other users...

In last month's DV Video magazine, they did a report on DVD-R media in different players, and the results were quite shocking !!! Hence why I only buy Apple/Pioneer media for total compatibility !!!

It's not the grade of the media (well...to a point) but mostly in the color...

I have 2 dvd players, one of them, a Mitsubishi DD-4001 which I got for free, is a great unit....except for one little thing...

IT WILL NOT PLAY ANYTHING BURNED AT ALL !!!.....I've tried almost every media and color CD-r there is out there, when the disc would go in, it imediately says "NO DISC"

Ya know what fixed it??? "pure silver" cd-r's !!!!!

Philip,

While I agree with you on the reflectivity issue, the color of the dye still has everything to do with the reflectivity of the strength of "Coherent" light, or laser light that is of only 1 single wavelength and no other....

The early dyes (cyanine dye ) was the only type, had a very high tollerance to error and therefore, only expensive WORM drives were the real first types...but due to their "exact science", few manufactures made them (Panasonic, Phillips etc.)..

Now we have Phthalocyanine dye and Azo dye(which is the best)....

The colour of the CD-R disc is related to the colour of the specific dye that was used in the recording layer. This base dye colour is modified when the reflective coating (gold or silver) is added. Some of the dye-reflective coating combinations appear green, some appear blue and others appear yellow. For example, gold/green discs combine a gold reflective layer with a cyan-coloured dye, resulting in a gold appearance on the label side and a green appearance on the writing side. Taiyo Yuden produced the original cyanine dye-based gold/green CDs, which were used during the development of the Orange Book standard. Mitsui Toatsu Chemicals invented the process for gold/gold CDs. Silver/blue CD-Rs, manufactured with a process patented by Verbatim, first became widely available in 1996. Ricoh's silver/silver "Platinum" discs, based on "advanced phthalocyanine dye", appeared on the market in mid-1998.

Unlike ordinary CDs, the reflective surface of a CD-R (CD-Recordable) is made to exactly match the 780nm laser of an ordinary CD-ROM drive. Put a CD-R in a early DVD-ROM drive and it won't reflect enough 650nm light for the drive to read the data. Subsequent, dual-wavelength head devices solved this problem. Also, some CD-ROM drives' lasers, especially older ones, may not be calibrated to read recordable CDs.

But the color of the substrate can help an older or single phase laser read a disc of a different color if there's enough power on the laser to do so. It's simply up to the manufacture to determine this...

So Philip, as you can see, the color of both the dye and the substrate has EVERYTHING TO DO with how a laser will read the disc..

Now if you want me to post about RW and Phase-Change materials, then I'd be happy to..

And again, to your argument, if color doesn't matter, then why doesn't all GRADE-A media play in the same player ????

AH HA !!!!! It's color and reflectivity...you say dual layer reads at a lesser power which is true...but it's also a different wavelength designed for that lower power...

Read the IEEE and dvd-consortium specs on dual layer sometime..

A place called www.atdiscount.com has DVD-R for .89cents, but only in 100 packs.

Haven't used them myself.

For Leebo, no you can not just rip a DVD to a double-sided DVD-R, all a double sided DVD-R is two standard 4.7Gbtye DVD-Rs stuck back to back.

Thanks, Philip. I knew that.
The previous poster asked if you could simply record an entire movie onto a 9.4gig DVD-R. I meant to explain to him that it was still ONLY 4.3 gigs per side.

At Meritline they go for about $15per disc, in 100 disc packs.

[teddy107]

yeah..I got afew from www.shop4tech.com a month ago and they are rock. 2X write takes about 22 mintes for each side and need to flip otherside. Good thing is those fit entire DVD with all subtitle,languages with menus and special feature like original. I use ifoedit to split and use neo express to author them. so far no problem. :P

[leebo]

teddy,

R U talking about the dual sided discs?

[Jason A]

Unforntuantly, I don't have $1500 laying around to buy the Pioneer media...and again, either Apple/Pioneer is all I'll buy when burning video discs....for Data, the cheap stuff is fine..

Now if a group of us wants to get together and buy that 100 pack of DS Pioneer media, then I'd be up for a 20-30 discs !!!

As for arguing the point about color and Grade A media....I'm not going to get into it...it's not worth it.. however....here's a site that shows how to tell and all about the colors and makers used..

http://www.cd-recordable.com/FAQ_Tech.htm#Color

Generally, grade B media has jagged or rough edges around the outer rings or air bubbles when the dye is sandwhiched in between the two discs..

Grade A media is nice and smooth !!

Yes $799.99 for 50 Pioneer 9.4gb DVDR discs is a stupid price.

You can buy 100 4.7gb DVDR discs for $170.00 usd.

Yes...but we're talking Pioneer media here, not lower grade stuff...
