When does your quality score go down?

vbimport

#1

my score always drops right when the scan starts.

is this when you get most of the spikes?

i never get anything lower then a 96 so i’m not complaining :bigsmile:

i always thought the spike comes at the end of the disc :confused:


#2

The quality score is inversely correlated with the PIF total score. As the PIF goes up the score goes down.


#3

but should you always get those pif spikes at the beginning?


#4

My BB MIJ Fuji 1133 TY’s all seem to spike around .25 GB which drops the QS to 97% Otherwise, my scans look pretty much like yours




#5

very odd.

you would think it would spike at random?


#6

I think it most often occurs at the end then the beginning is next likely.


#7

My quality score normally goes down as soon as I click the scan button. JK. :slight_smile:
Both my drives seam to spike around the 1.5 Gb mark with TY02 at 8x and 12x, @ 16x they are always high around the 4.0 to 4.3 gb, maybe media maybe the drives. Still very good burns overall.


#8

Yeah…my scans are still great


#9

In my opinion, such regular spikes are due to the media not the burner.
I also have seen “spikes at the exact same spot” for a given media and given spindle. But it disappeared after 10 or 20 discs. I assume the stamper had dye problem while producing those media. (Not even a real problem… a single spike of ~6 we’re talking about here. It doesn’t make any problem, just lower your QS and prevent you to boast your scan. :slight_smile: )


#10

Happens to me sometimes too…
I’m not complaining either…Never had a QS lower than a 97.


#11

Also mine YUDEN000T02 (1125) had the “defect”… a PIF 8 spike at 0.5… no matter at what speed you burned and in what drive you scanned. =) The same spike at the same place has been reported from other users too.


#12

so it sounds like a media problem :iagree:

that makes sense too.


#13

FYI-I’m seeing the same problem with a recent lot of TYG02’s… Unfortunately, I’ve had a run of about 25 disks in a row with a PIF of 6 right at the 0.07 Gb mark. Doesn’t seem to affect the playability but I don’t like to see it.


#14

yea i never have any problems either, but always looking for that 99 score :smiley:


#15

what burner and speeds ya’ll used for that?


#16

Only 8x


#17

I’ve had the same PIF 8 spike consistantly. My last spindle “Fugi YUDEN000T02” had a rise in PI at around 2.5 Gb. But not enough to worry about or affect playability. Just getting ready to start a new batch of 20 burns with a new spindle. I imagine the rise will not be on the next spindle as I never saw it on previous spindles :slight_smile: :slight_smile: :slight_smile:
