    This fool is a troll. This is NOT a serious post. Get suckered in an respond at your own peril. Look at his other threads like this one https://forum.videohelp.com/threads/358823-DVD-disc-Fungus
    and
    https://forum.videohelp.com/threads/358471-Questions-quality-Philips-DVD-R-CMC-MAG-M01?...51#post2265051
    and you will see that either this guy is the stupidest SOB on the planet or a troll. Either way, whatever you post, he won't listen to it.

    General info

    Q2 = none, a theory spun by magic fairy's to promote their brand as superior to others.

    Reality = Store between felt sheets in a dark place with very low humidity and they should last years.

    Q3 = Q2 reply of none and the promise's made by those marketing magic fairy's again

    Printed side has data (scratch it and the disc is toast), this printed side is bonded to an polycarbonate layer having a thickness of less than 0.10mm and in 50% of discs produced also includes dye's used by dvd players laser in read mode to determine between cd or dvd is inserted.

    The remaining 2nd polycarbonate layer is thicker, a supporting layer for the flimsy data layer. May include dye's in cheaper brands and can be sanded to remove severe scratch's in the case of data recovery.

    Final note: NOTHING will protect your media except handling and storage with care.

    That is all you need to know about cd / dvd / bluray media construction

  5. Hard coating protects recording surface against scratches and rough handling

    I don't know if it really makes any difference. I don't think they make them in DVD+R.

    If your discs don't claim to have some kind of hardened coating -- they do not.

    I gave you a link which is pretty clear on that.

    Don't give up now, jagabo. Maybe you two can get this up to 100 posts, especially if Bjs jumps back in to help.

    ...and ignored advice here and in hundreds of previous posts that the brand is outsourced generic trash to begin with.

    I don't know why the O.P. uses DVD+R in the first place. They look like blank discs to some players, which won't accept them. DVD-R is compatible everywhere -- assuming they're not scratched.

    The only type disc I know of that reportedly is built to be more scratch resistant is DVD-RAM (Panasonic, Verbatim). But most players won't handle DVD-RAM.

    I second jman98's sentiments. Now and then it might be good to shout at the wind, if for no other reason than venting might feel better for he who vents.

    ^Now you've done it. He'll be asking questions on differences between +R and -R next, and why you think -R is better. Lets just hope no one mentions bitsetting to him.

    Wait a minute...

    Main difference between +R and -R is that you get a better class of fungus on one.

    I'm having trouble deciding if he's a troll or just an idiot wanting attention.

    Which may be the same thing.

    Either way, he's a moron.

    A nice find.

  18. I read the review CD and DVD structure but does not say if the DVD + R has some protection for scratches not damage the data layer and the layer of reading
    Quote Quote  
  19. Discs with a hard coating have an additional thin coating outside the polycarbonate layer on the data side of the disc. Most discs do not have that coating, that's why it's not mentioned in the CLIR link.

    Why stop at 100? We'll get there in no time just by re-posting previous answers the O.P. has ignored.

    Well, OK, maybe the O.P. has a reason for wanting to know this stuff. I wonder if he has others looking it up for him because he's been banned from Google and Wikipedia?

    Nobody knows. It's a trade secret.

    If you had read the links you would know that they are all responsible for reading the disc. The actual data is held in the dye layer. The reflective layer is required to reflect the laser beam back to the read head. The two polycarbonate layers are required to protect the inner layers and hold everything together. The bottom polycarbonate layer must remain relatively free of scratches in order for the disc to be read.

    WOW!!!!!
    That is way nicer than what is really required for this person from the shallowest end of the gene pool!!!!!!!

    LOL!!!

    Is he really a "troll" or just more than 20 crayons short of a full box ?!?!?!?
    LMAO!!!!

    I can not believe that this idiot is still posting and what is even MORE amazing, are all the people still replying to his post's!!!!!

    Talk about self-centered and needing to get a life and stop paying attention to worthless waste of time post's instead of thinking they are helping someone who is either beyond help or just trying to jerk everyone around to feed themselves!!!


    He obviously does not, and never will, have a clue or is a serious loser with no life and nothing better to do!!!

    Talking of 4-layer disks, did anyone ever handle a DVD-18 (or a DVD-14 for that matter) ?

    Phillips must have made some. They made everything else

  27. In closing, just answer me what's on a DVD + R that protects data and the disc from scratches






    1 Layers of polycarbonate are the only protections for scratches on a DVD + R?


    2 The reflective layer is the layer responsible for reading the disc?


    3 how deep of a scratch on the bottom layer that does not affect the reading and the data disk? DVD + R has some tolerance in mm or cm for scratches damaging nothing and reading the data?
