What is it? I am quite new to DVD burning....I have burned around 30 DVDs...N today a media I burned... Which is a RICHO media but it is a CMC dye...There is a visible line from the inner of the DVD until the outer of the DVD... N the color is almost the same as the non-burned area.... Is that called Coaster?
A coaster means "an unreadable disc."
So what is the line on my DVD burned?
A circular line may be due to a short-term laser power adjustment (DVDs often have circles of varying shades/reflectivity because of normal power changes during burning). A radial line is most likely a dye defect from the manufacturing process.
It is a line from the inner side of the DVD to almost the outer side of the DVD...So it is a dye defect?
Such a disc is considered a bad burn?
That is considered as a bad "disc". The quality of the burn can be determined with PIF/PIE scans if it's readable.
Run a quality test as described in this thread:http://club.cdfreaks.com/showthread.php?t=96285
It will show how many (hopefully, correctable) errors are introduced in the reading process and where the disc is on a scale between a perfect burn and a coaster.
This is the line I am referring to...The scan is quite slow...
How is it?
I never saw something like this before. =\ The scan is also bad.. so throw the disc away.. and reburn.
Yeah... This is what I am gonna do... Too bad... I went to buy media yesterday...There were two RICOH 8X, one +R and another one -R... I was wondering which one is true RICOH n which one is CMC... So I bought two...Went back home n tested... +R is RICHOJPN 02... -R is CMC... I get good quality scan on RICOHJPN media... While this CMC makes my drive go haywired... Another thing to note... When using RICOHJPN to burn my data... 8X takes around 8 mins which I think is normal... While CMC takes 10 mins plus which I think is... CRAZY... Is CMC really that BAD? Oh well... I only have 6 CMC left... It's fine...
Lol ... that much damage ... but the disk is still readable (no PO errors)
But what the hell that line is? I have 2 CMC burned like this...
no idea .... its probably a manufacturing defect, but it completely like any defect I have ever seen.
I believe they're called "coasters" because, when they're really bad, you might as well use them as a coaster to set your cold drinks on because that's all they're good for.
Cool! 100,000 PIF but still no POF. This is probably a record.
I guess it's a dye defect. But make sure your hair isn't in the drive. :bigsmile:
