    Are the Verbatim 16x DVD+R made in Taiwan any good? Or the ones made in Malaysia or Singapore?

    They are excellent discs. Made by CMC Magnetics. Many people find that difficult to believe, but the reason CMC Magnetics is unpopular on this site has little to do with actual quality rather than other issues.

    I haven't come across discs like the one's you are describing.

    I haven't come across a MIT Verbatim that was CMC mag's, and the last CMC mag discs I got were still utter garbage. They had POF errors all over the place after about 3.5Gigs in.

    Unless CMC has done a total about-face in quality in the last two years, I still won't touch them.

    Just about every Verbatim disc manufactured in Taiwan is manufactured by CMC Magnetics. The stampers used have the MCC/MKK M-code, but the production is by CMC.

    High POF errors around the outside of a disc can mean several different things: 1) tilt caused by paper labels, the wrong ink-jet coating, or poor bonding adhesives; 2) scratches on the outer edge; 3) poor dye distribution; 4) poor edge cleaning; 5) improper fitting of the sputter mask; 6) imbalance of the disc; or 7) incompatible firmware. I have found examples of all seven, but the last one is the most common. In almost every case I have seen where I run into a large distribution errors at the end of a disc, I have gone through all the testing to identify the problem. If the disc has a paper label, it is cause #1 in every case. In almost all other cases, a test recording on a different drive eliminates the burst at the end.

    As for CMC, they did have a tilt problem caused by faulty curing ink-jet printable coatings about three years ago. It affected only DVD-R media, not DVD+R, which used a different coating. This problem and a few others did force them to do a complete about-face in production, and Verbatim was not alone in putting pressure on them. Today their biggest problem is the reluctance of some drive manufacturers to support their M-codes and the difficulties in making discs of identical quality on a variety of differnt production lines. (They produce more discs than any other manufacturer.)

    Hey JoeRyan,

    Do you happen to know or have a list of what dvd products are currently being made in Mitsubishi Kagaku Media's (Verbatim) Singapore plant and in the India facility?

    Do you have an opinion why we are seeing more Verbatim MII DLs in the US now?

    I have heard that the Singapore plant manufactures only DL media, and I have read reports about MBI's producing Verbatim DVD+/-R media as well as DL discs. I have not personally seen these products, but members of this and other forums have run into those products.

    A brand can shift plants for several reasons. Cost is usually the most common reason, and that includes lower cost of production as well as the reduction of levies. (Levy reduction is why Viet Nam and some other countries are now manufacturing CD-Rs for Taiwan-based manufacturers. With the fall of the dollar, we should not be surprised if optical disc manufacturing moves to Alabama, once the site of several tape factories.) Another possible reason is limited capacity at a particular plant, although in the case of DL there is not enough demand yet to make that an issue, I would guess. If Verbatim has not shifted to inverse stack production for DL media, then they may be facing a cost disadvantage with 8X IS DL from Ricoh, the developer, whose discs are manufactured by Ritek. These are just guesses because I really don't know why they made the switch.

    Thanks for your info JoeRyan, it's appreciated!

    Is there any test a regular user can use to tell if a disc is Inverse Stack production without specialized equipment?

    Not really because the final disc is trying to mimic the DL DVD-ROM.
