Optidrive Control - Disc quality?
#22

Didn´t tried this media in a Liteon, was 4x the max. burnspeed?


#23

4x and 6x possible


#24

Lite-On iHBS212 HL05, 18,99 GB burned at 6x

sold as "Kodak 6x BD-R"
MID: UMEBDR016
made in China by Umedisc with Anwell Smart-BD line
this disc has a very strange cloud like and circular patterns in the recording layer after it was burned


#25

Same with my Kodak, but don´t know if only some discs have the clouds or all


#26

Kodak 25GB / UMEBDR016

Burned with Pioneer BDR-209EBK @4x



#27

The Lite is IMHO sensitive at highest read speed.

Maybe a LG and Pioneer have less problems and show a perfect TRT

My older iHBS112-37 as scanner shows different results



#29

Writer: LG BU40N
Firmware 1.02
Media: Kodak BD-R 25GB 6x
MID: (UMEBDR016)
Burn Speed: 4x
Software: Nero 12 Ess.
Burned 2018
Scanned 2018

Again “cloudy” media

Poor readability overall, it don´t like high read speed

I have to use an other Lite, my normal scanner don´t recognize this media

Writer: Panasonic UJ273
Firmware: 1.00
Media: Kodak BD-R 25GB 6x
MID: (UMEBDR016)
Burn Speed: 4x
Software: Nero 12 Ess.
Burned 2018
Scanned 2018

Again “cloudy” media

What happened here? I guess it´s the shifting from 2x to 4x, the write strategy of the Panasonic wasn´t good. But the media have also problems in general

I have to use an other Lite, my normal scanner don´t recognize this media

funny scans on Samsung SE-506BB, day after burning “mountains” are moving :slight_smile: Scanning @ 2.2x shows similar graph like on other drives.

Yo :wink:

I guess your Kodak don´t have any clouds on the dye?


#33

Well, has anyone managed to take a picture of those clouds? The only strange thing I observe on those Kodaks is clearly different tint of reflection depending on the distance from the edge. In the centre dye seems more greenish and then turns more into purple towards outside of the disc. When looking in direct sunlight whole area seems to be uniformly dark grey.

Here the best picture I could take to illustrate the tint change.

#34

OK, today I tried burn on another drive @4x (but buggy FW of Samsung burned @6x) and I got some clouds, maybe those discs can only be burnt well @2x? (I burned 3 discs on BD-5750L @2x and all of them look nice like in previous post, however last one failed @14GB).

Today’s “cloudy” media (burn rings from Samsung for free):
Samsung SEe-506BB TS00 @4x (effective 6x)

and scans…

#35

This media seems to be awful, mostly

Don´t think it depends on the burn speed


#36

Sure it’s an awful media. But I’d assume that burn speed could impact. Even on crappy Sony powered by RITEK BR3 I can see some visual difference between 2x and 6x burn. If you still have any Kodak discs left try to burn @2x if your writers support that speed.


#37

Already tried one

But the clouds wouldn´t care about the write speed, the media have a bad production.

Sure, with lower speeds the overall error-rate is lower, but the clouds are still the problem

Another burn, different burner:

Lite-On iHBS212 HL05, 22,82 GB burned at 6x

sold as "Kodak 6x BD-R"
MID: UMEBDR016
made in China by Umedisc with Anwell Smart-BD line


#40

Liteon iHBS 112. Burned with cdrskin (options -force -speed=6, but drive slowed the speed down to 4x around 3GB mark - this spot can be seen in the scan). -force -speed=0 yields also in a 4x burn.

“Picasso” branded BD-R 6x (non-printable) from aliexpress. 5 discs burned, this was the best.
