Disc Quality and Pioneer BD writers

vbimport

#1

Trialing Opti Drive Control 1.70 with my Pioneer BDR-208EBK, but it won’t do most tests, in particular the Disc Quality test on either DVD-R 4.7GB or BD-R 25GB.

Are there any Pioneer BD burners which will?

Or is there other software which will do a disc quality test on BD-R 25GB using the BDR-208EBK (firmware 1.10).

TIA

Pioneer drives cannot do quality scanning with any known software.

(some do, but only select drives, only for…DVD media?, and they are not known to be reliable.)

Would LiteOn iHOS104-32 do reliable Quality Scans?

Or if not, what drive(s) would you recommend?

thanks

It, too, would not be reliable.

Can you find an iHBS112/212/312, or an iHES208 or iHES212 (or 108/112)?

Or if you can do an external drive, a Samsung BD-Writer (SE-506AB/BB/CB)?

By some small miracle I find I have a Samsung BD-Writer (SE-506CB/A UBD) which seems to do the job.

Here’s a newly burnt M-Disc BD-R 25GB MILLENMR1 23.13 GB data (printable but bearing only small text ID) - less than fantastic for a disc costing about $AUD7 IMHO… Will this really be still readable in 3015…?

Compare this new burnt, unprinted Panasonic BD-R (printable) 25GB LM-BRS2MWE10 MID: MEIRA1 (001). Heaps better, I think…


#7

Yeah, it looks mediocre for an initial scan, but it might last!

Those Panasonic discs might last just as long, too. And with a lower initial cost. :bigsmile:

Had me worried, did 2 more M-Disc scans.

M246 newly burnt, not printed - not too bad:

M233 burnt 22Mar15, my first M-disc ever. Inferior to M246, but much better than M245 (the first M-disc scan shown).


#9

All burns done with Pioneer BDR-208EBK, firmware 1.10.

M-disc burnt @ 4x, the Panasonic @ 6x.


#10

Those look much nicer & are preferable to the second-to-last M-DISC burn you did (M245).

What is the significance of LDC and BIS? What is “good quality”?

Jitter always seems to be the same regardless, does it have any significance?

TIA

LDC: easier to correct digital errors. lower is better.

BIS: harder to correct digital errors (but still correctable, up to a given limit). lower is better. lower = less need to apply deep error correction = can be read at full speed.

Jitter: uniformity of the (lands and pits) in the disc. Lower jitter = better physical uniformity = easier to read in a mechanical sense.

I could go more in-depth, but I leave that to various articles littered elsewhere on the forum (which I’ll link to at another time, if so desired)

Yes if you could give those links please.

Do you have any limits which you recommend LDC and BIS to be under?

TIA
