Can anyone recoomend a Good writing Strategy?

Hey all!

I have looked at the tests in the Writing Strategy threads and cannot see any recommended strategies for the CMC MAG AE1 on a Lite-on SOHW-1973S drive…

I am currently in the process of doing some, however, rather than making loadsa coasters can anyone recommend a different strategy as these discs are quite random…

You are better off tossing those disks. All the write strategies in the world can’t fix crap media.

There’s nothing wrong with the CMC media. The LiteOn’s have never burned -R very well though. Your best bet is to just slow it down one notch. Or get a NEC or LG to burn it with. :wink:

Well last night, I changed a couple of the strategies, and updated the firmware and it seems to have made quite a few good (well “better”) burns now… just got to see if the trend continues… I Will post these in the test thread as well…

Also, sorry to mods if this is in wrong section…

Burned Using SOHW-1673S Diff Firmwares…

  1. CMC MAG AE1 Using JS02 Firmware…
  2. CMC MAG AE1 Using JS07 Firmware…
  3. CMC MAG AE1 Using JS0B Firmware…
  4. Omnipatched JS0B Firmware with Learned Media Reset and Prodisc003 Strategy… (at 4x Burn speed)
  5. Omnipatched JS0B Firmware With Learned Media Reset and TYG02 Strategy…

Yah, JS02 is pretty old. Looks like JS07/B did the trick…

I would call the JS0B native result reasonable - not superb, but no serious vices, and compared to how it improved from JS02, I’d doubt that the drive is capable of doing much better with that media.

Is there a calculation error somewhere - they look the same length, but:
#3 - PIF ave: 0.08 / max 3 / tot 1828
#5 - PIF ave: 0.12 / max 3 / tot 1403
How does the average go up by 50%, while the total goes down, when the length is the same or very close?

Easy, the average has nothing to do with the total count.

I never pay close attention to the actual numbers. The shape of the graph (indicating problematic regions or patterns) and average peak values depicted by the graph (e.g., in the ball park of 40-60 for JS0B stock) are much more useful, IMHO… I always ignore the numbers at the bottom because they don’t seem to mean much and have never been all the consistent for me.

Also, the difference between JS0B stock and JS0B strat-reassigned is pretty low. In the grander scheme of things, the difference there is negligible, so I’d stick with stock; I personally don’t use strat reassignments unless I’m overspeeding or unless they mean the difference between a burn and a coaster.

Thanks guys for advice an info…

The later burns work a lot better in my PS2 but as a general rule, im gonna get some MCC or TY media next time.

Its a shame you couldn’t buy “tester kits” of 10 discs all using different media to see which works best for your particular drive.

Ask and ye shall receive.

Well F**k a Duck… Do they ship to UK? Or anyone know of any “tester” kits for sale in England?

SVP do sample packs…

{DV 3000} DVD-R/RW “Low speed” Sample Pack

1x {DV 3237} Unbranded Silver Topped (2x)
1x {DV 3246} Datawrite (4x) Yellow
1x {DV 3197} Tuffdisc (8x) DVD-R
1x {DV 3202} Datawrite ‘Titanium Silver’ (8x)
1x {DV 3146} Ridisc (4x)
1x {DV 3233} FREE 8cm Disc Datawrite (4x)

It appears there’s a sample pack in each category, sometimes a low speed and a high speed, though there is a lot of e-net media in the lists.

I have test-written and scanned some of the Datawrite media I was given (writer, Pioneer 109, reader, CRX320E), and the results have me checking my scan platform.
A nasty spike in the middle of the first 6x zone (on CMC MAG AE1), but otherwise good - with a 1.55FW burn doing 8x, and a 1.57 going up to 12x (tail end back to 8x) with no loss in quality over the 12x zone.
The spike is the same on both examples, and not repeated on a scan in the 109.

Interesting, I bought these discs from SVP and must of skimmed over that section in the quest for my first DVD-R purchase.

On another note… I have now burned over a dozen discs using the TYG02 code (forgot to change it back :eek: ) but the scans are still looking very good indeed - I have yet to try the Film backups in a standalone player, but will be doing so tonight to see what the result is. If they come out fine then I’ll probably buy these discs again for my own personal non-important data but get some TY for the important stuff.

Last burn image attached.


you could have a bad batch, my 1673s & nec 3500 burn the datawrite titaniums very nicely.

1, 1st burn on new 1763s JS07 @8x
2, 1st burn with JS0B @8x, no learning reset
3, nec 3500 LD 2TD @6x (burned @ 6x because 8x was not as good as litey @8x but can`t find scan the post.






and the final tranfer rate test.


Well, I forgot to say that I have tried them in a standalone player and have not come across any read errors as of yet…

I am going to keep this write strategy until I buy another batch (they seem to be ok now so am going to use them still but like above, for critical data, gonna purchae some TY media) then i’ll see if they still burn ok and if not, revert back to default strategy.
