Unfortunately the current firmware only supports these discs at 4x maximum!

We can see that the disc has the text “DVD+R DL 8.5GB 8x” printed at the top and the text “Mitsubishi Kagaku Media Verbatim” printed on near the bottom. We took a close look at the numbering on one of our sample discs. The serial etched into the plastic hub is EX54QKI6061425. The holographic text on the inner disc reads ZD5289-DVR-X851-P02 ZD5281-DVR-X850-03.

Test burn at 4x.



#3

Excellent results on the Kprobe scan!



#4

Wow :eek:
That’s really nice.


#5

And now - something a little different.
8x burn on MKM003 using MKM002 writing strategy ( thx to Dee-27 ).
Burn speed dropped to 6x near the layer break and continued on at 6x on the second layer.

@Wesociety,

You could have down the 8x for this media yourself with the MediaCodeSpeedEdit tool from ala42 or am I wrong here?. But anayway, nice test :slight_smile:


#7

I’m confused: why does MKM produce three different DL media?


#8

MKM01 is 2.5x rated speed MKM02 4x and MKM03 8x. At least that’s how I see it.


#9

You are right, but I was talking with Dee-27 and asked her to help me out while I was working on something else. :wink:
Thx Dee! :flower:

  • MKM-001 -> 2.4x-certified media (though companies try to make their drives overspeed it to 8x)
  • MKM-002 -> 4x-certified media (probably just something that they were toying with)
  • MKM-003 -> 8x-certified media, will be released soon

MKM-002 is not in the list of “approved” +R DL media codes according to Philips Licensing (which regulates the use of +R/+RW/+R9 media codes). This, coupled with the fact that MKM is jumping straight to -003 without ever having publicly mentioned -002 is why it is believed by people that MKM-002 is just an interim test media type that they don’t plan on releasing.

So in reality, there are only two types. Not everything that you see in a firmware really exists. RITEKG09 appears in the NEC firmware, but that doesn’t mean that it has ever existed.

Thanks Code65536 for your explanation.

Understood. Thanks for the explanation code65536.
