Liggy & Dee ND-3520 Modified Firmware V1.UF Now With PI/PIF Scanning & Bitsetting

Backed up WhiteChicks using DVD Shrink and Burned using Nero @ 8x although i could have burned it at 12x with firmware v1.UE.

Here's some scans that illustrate what I was talking about in an earlier post. First is the NEC 3520A write strategy I got with a 12x burn on Fujifilm TY02 DVD+R media. Second is the NEC 3520A scan of this 12x burned disc at 5x 8ECC and shows an extra high PIE area a little after the burn speed exceeded 12x in the last portion of the disc - I have seen this same high PIE/PIF in this same zone on other scans from 12x burns. Third is a scan from a 8x burned disc of the same batch of media at 5x 8ECC. At 8x burns the first zone (approx 4x write speed with the 8x write strategy) produces a higher PIE than the 6x speed used in that zone with the 12x burn strategy and the last half of the disc shows no high PIE/PIF areas. So if I could have a write strategy for this media that would start like the current 12x burn strategy but caps the max speed at around 10 or 12x and no higher, it looks like it could produce the best of all - is that possible?

An 8X burn has to start at 4X. Its not possible to start them any faster.

Ritek R03 burnt@8X, I think it's Rev.02 because max. burn speed was 8x with stock firmware and 8x with V1.UE as well.
Read Speed in Nero CD-DVD Speed first was set to 12X, because the result was so great i tried with 16X again. Watch the result
Thanks for your great work (especially with concern to bitsetting)

Here are my two best burns with 1.UE
First is Fuji 8x/Yuden T02 burnt at 16x. Pretty good burn as expected.
Second is the surprise!! TDK 4x/RicohJPN R01 burnt at 12x. They were ok before, but never THIS good!!

Yes but is it possible to make a 12x burn strategy like the current one but that doesn't go all the way at the last speed changes? Like say 10-12x max rather than currently it goes up to over 13x at the end. At the point only Just beyond 12x appears to cause higher PIE/PIF as can be seen on my posted graphs. Could an alternative <12x strategy be created?

This is Verbatim data disk burnt with 1.UD firmware

It's DVD+R Verbatim code: MCC003 burned @ stock rated 8x


I haven't tested it at higher speeds yet (I think alot of people have already tested this media) anyway I wanted to mention that this was in a batch of 50 that I got from the 200 disc for $50 promo supermediastore was having last week. It included 100 verbatims DVD+R and 100 Linkyo's DVD+R (of which I have the linkyo's scanned on page 29 of this thread.)

One other Note: When I opened the package the top 2 discs were seperating (layer seperation) making them coasters out of the box. I don't know if I got old/crummy media or if they were damaged in shipment because of the horrific shipping policies of sms. The rest of the discs in the package of 50 seem fine upon visual inspection.

In all it looks like the linkyo's with opto8 code are the best of this bunch. Thanks liggy and dee for the firmware.

Unfortunately no, not without removing the 16X burn option on this media.
CAV burns @12X will always reach 13X


@ITman
Nice burns. I like RICOH media.

@790
Nice burn on that MCC003

@Beel
Revision 1 and 2 at 8X. Nice burn though.

Any hope for getting PRODISCD01 Double layer media supported?

Imation 8x +R Burned at 12x - 1.UE
Nec scan at 5x - 1ECC (no Transfer test posted, as it's perfict as usual)
+ Kprobe of same disc for compair

fuji 8x burn't at 8x just can't get a good burn on these

I think we can probably manage that
I need the full media block from DVD Identifier though

Hi, Dee!

Since my results with the Ritek R03 (I think it was Rev.2) were so great (last posting with pngs), would it be possible for you to change the max. write speed for this media higher than 8x in the next firmware version? I could post results with the higher speed if you like.
P.S.: Would you need some extra media info?

The stock firmware blows it off unfortunatly http://club.cdfreaks.com/showpost.ph...2&postcount=12

Please implement 12x speed to this
Thanks
Really good work

Your scans from an 8x burn with Fuji 8x media shows the same higher PIE during the initial 4x burn speed zone that mine do. I've noticed that with 12x burn speed since it starts at almost 6x speed in that zone the PIE is low, I wish the NEC could start at 6x instead of 4x for an 8x burn or that the 12x burn could burn the last portion of the disc at a slightly lower speed. I think that would yield the best results with the NEC and FujiFilm 8x DVD+R TY02 media. It can't reliably do good 16x burns with that media in my tests anyway so I think trading the 16x strategy for a modified 10-12x strategy would be a good compromise.

I agree too with your comment regarding 6x from start. I have same experiences of this. Always 4x is worst as 6x or 8x. Start from 6x for 8x burn will be drastic improvement of quality with NEC burners.
Dee: Please start investigate this possibility...thx.

This is MCC 01RG20 (4x burn at 8x)....

Believe me we have, it's not possible for us to implement this change.

Who have response to do this change? Only NEC???

Please speed up the Ritek R03-002 to 12x or 16x if possible. All the information you should need (media code block etc.) is in the attached txt file.

Personally I'd trade the low yield 16x burn option for the FujiFilm x8 DVD+R media for a modified 12x burn strategy that would limit the speed at the end of the disc - that would be a good alternative too.

What do you mean by limit the speed at the end ? =)

Hi

I would really appreciate if someone would take the time to clear this question for me, plz :-)

The differences are explained in the text files supplied with each firmware revision from Liggy and Dee.

See my earlier posts and scans in this thread for examples. But basically its been observed that the FujiFilm 8X DVD+R media works well from about 6x to 12x burn speed, but is lower quality when the burn speed is lower like 4x or higher than 12x for some zones of the disc burning process. With the current 8x burn strategy there are 3 zones, the first portion of the disc is burned at a speed about 4x, the second portion is about 6x and the last half of the disc is burned about 8x speed. With the current 12x strategy its starts at about 6x and shifts higher and higher several times until near the end of the disc its higher than 12x, in fact a little over 13x and I've noticed some higher PIE/PIF spikes right after it exceeds the 12x speed - see the earlier posted graphs for details. If the strategy could be modified to stop at about 12x and no higher near the last 2 zones (near the end, outer part of the disc) I think it would yield the best quality burns - better than the current 8x and 12x strategies. If one has to give up the low yield 16x strategy for it, I would do so.
