    Hi guys, I´ve just bought a 8160 DVD recorder, and on the 2 Ridata DVD-r medias, I burned, after the process we can see some small darker points spread on the media surface, The poins were not visible before the recording process, Could it be a defective midia, it plays flawlessly, but could it shorten its lifetime...

    I posted a picture of the "problem" here:

    Do a scan with dvdinfopro and see if there are any errors,if not i wouldnt worry about small spots like that,ive had bigger spots with no ill effects.

    Sorry I said they were Small, The Black arrow points to it...

    The Disk was a 4x midia and I recorded at that Speed...

    As I said, Im new at this world , And I will be doing a VHS to DVD in large scale to a Client, and the idea of my client loosing Data with a short time is disturbing me...

    The Philips DVD+RW media I burned didn't have any black spots, but the 2 Ritek medias I burned Had, on one of them, Appeared some blotches similar to finger prints and coincidently there WERE fingerprints exactly over the blotch, that keept there after I cleaned the fingerprint at the media...Before the recording process, I looked at the disk and there were no black spot, the surface , before the recording has a diferent color, after that it gets a little opaque, and only after that the points appears...

    A week before buying my recorder, I Saw the same on a disk burned froma a friend of mine... I wander if its not a Low end media feature, because i leave in Brazil, and Many things that we have here are low end ...

    Thanks to all...

  7. I've been experiencing exactly the same thing. The other day I happened to notice strange dark spots across a DVD-R I'd just burned. (Using Pioneer 106 & Ritek G04 disc @ 4x speed). The dark spots mostly seemed to be where there were tiny specks of dust on the disc surface, but if I cleaned the disc the spots remained and seemed to be within the dye layer.

    I tried several more test burns with different media types (Maxell & Taiyo Yuden), and even if I made sure that the disc was spotlessly clean before burning, I seemed to get some spots appearing. Using a lens cleaner in the burner didn't make any difference either. A scan in dvdinfopro did not show up any read errors, and the discs seemed to play fine in a pc DVD-ROM drive and also my standalones.

    I checked through discs that I've burned over the past few months, and could see that the problem first started about 3 weeks ago, but has been getting progressively worse. I don't think it's media, as it happens across different brands and dye types. In the end, even though I'm not getting any read errors, I decided it was probably time to upgrade my burner so I bought a Pioneer 108 yesterday.

    Have done 10 burns already without a single flaw, on Ritek G04 (Ritek printable), TYG01 (Verbatim Pastel), MCC (Verbatim Datalife) and Maxell DVD-Rs. Nothing else has changed so it seems likely that the problem lay with the drive. I'll take the 106 apart to have a look at the lens - my hunch is that there's going to be dirt/dust on it that the cleaner disc couldn't shift. I might back-up some of the more important spotty discs in case there is an issue about data-loss in the longer term.

    that dark spots is cause by the dust on the disc, even a very very tiny dust will cause that dark spots after burning.
    take your disk under the strong light before burn, then you will see the dust clearly. because those dust cover the surface of the disc and it block the laser from burning it.
    But most of them will play fine in pc or standalone.

    Vampyr, it really can be that, because, when I first saw that, There were those black spots but at the end of the disk, there was a blotch similar to a Fingerprint, and It indeed har a fingerprint over the disk , I didnt know that DVD recording was such more sensible than CD recording. Never Had such kind of problem burning Cdrs...

    PS: My recorder is a LG 4160B, brand new...

    Thanks...

  11. I can verify that any dirt or fingerprint you put on blank media get BURNED into the finished disc.

    I noticied a fingerprint on a DVD-R just the other day right after it came out of the burner. It was mine, and it was burned into the finish. I could not wash it off, even under soap and water. The disc froze about the half way point when I tried to play it back.

    Now I check every disc carefully before and after burning, wash my hands, etc. Keep blank media in factory cakebox before burning, keep cakebox cover on at all times.

    I also clean food and greasy crap off of rental and Netfiix discs too before playing on my home theater rig ...but that is another matter entirely

    Ok, so that's it...

    Another question, what could I use To clean the surface of the disk, Its a little difficult to remove all the dust from the disk, it might exist something effective to clean the disk...

    thanks...
