OH MY, I just bought two of Medianca branded cdr's from local pc shop on impulse and thought I'd might as well tes em out and kprobe the results and I am extremely happy to say they are AMAZING!

The cdr's are sold in jewel boxes, packs of 10 for £5 pictured here

The CD info kprobe reads is

The burn speed rated on them is 52x, I used nero to burn 703MB of mixed mp3's using DAO and finalized the session. Burn time was the quickest I've ever seen too



and Kprobe write stratefy results



Very impressed with these and as you can see the c1 rate is most ipressive, the lowest of any cdr I've ever tested so far, I think I've found my new regular cdr's

I have a LTR-52327s with QS09 firmware btw

I also bought the CDRW variant (rated 4-12x) and ran a simular test on those but with mixed data and again, VERY impressive results compared to all other media I have tried to date

and kprobe results

You gotta like those, mrk1283. How are the Nero CD Speed ScanDisc results?

I've never actually used neros cd speed yet but give me a few moments while i crack another cdr open :d

aren't the results for the CD-RW disc too good to be true?

i'm not doubting you, but to the best of my recollection, from various scans of rdgrimes, CD-RW discs always have a much higher level of C1 errors, even the best media!

Nero CD Speed test results

Initial

Nero CD Speed CD quality test results were 100%, no errors

I'll do a complete eras-format of the disc and reburn the same data to the cdrw to make sure and post back shortly. I'll do this by imaging the disc in nero then erasing>burning the image back

Just done a re-run, after a reburn it appears that they have taken to thenature of a cdrw, more c1 errors (but not that much) and no c2 errors. The strange thing is my infiniti pro cdrw which is months old has fewer c1 errors than the new medianca one so I guess you could say that the medianca cdr is 100% perfect but the cdrw is just "ok" or "average"

I did a double burn, one on the above media and one on a spare Infiniti Professional 12x cdrw I had with the exact same data.

Medianca CDRW
kprobe:



Infiniti CDRW
kprobe:

And Finally, Results on another CDRW, this time a Verbatim 24x (650MB)

Again, burne din Nero with 649MB of data and scanned with KProbe






A bit worser than the medianca!

Many thanks, mrk1283.

Update with new liteon qs0b firmware, see here

LG GCE-8520B OC:Firmware: 1.04

HP 48x Rated Burned @ 48x 100% green.
Kprobe 1.1.2.6 shows quite low number of C2 error too, I'm very surpise how good these are I thought they would suck like other CMC disks.
ATIP: 97m 26s 66f
Disc Manufacturer: CMC Magnetics Corp.
Reflective layer: Dye (Short strategy; e.g. Phthalocyanine)
Media type: CD-Recordable
Recording Speeds: min. unknown - max. unknown
nominal Capacity: 702.83MB (79m 59s 73f / LBA: 359848)

I also used the Mitsumi 48x rated (Postech) but was only able to burned it @ 16x, just like the cheap generic 48x (Postech) I got before that, anyways My LG GCE-8520B shows 100% with scandisk but my Liteon 166s show lots of yellows and a few red squares.

I'll be reviewing those HP 48x CMC CD-Rs in the next couple of weeks....

New drive entry
Benq 4824W C.FZ

Undranded 48x
Manufacturer : Ritek
Usage : General

Burned 100% green at 40x

Scanned with Ltr-52246s 6s0f

Thanks, David. I'm sure that won't be the only entry for the 4824W.

Here are some more "exotic" media:

Code: Select all

LiteOn LTR 48246S
Firmware SS0B...........Samsung/Plasmon 80min 48X...............48X
........................Fujitsu-Siemens/CMC 80min 48X...........48X

These both cost 2.99 Euro for 10 slimpacks (cheap here).

ATIP from SmartBurn 3.1.4:

Code: Select all

Samsung
         Disc Type = CDR (B-)             
          Material = Phthalocyanine
           Lead In = 97:27:18
          Lead Out = 79:59:74
  Nominal Capacity = 702.83MB (79m 59s 74f/LBA:359849)
Manufacturer Maybe = Plasmon Data Systems Ltd.
Smart-Burn Speed Limit = Wrt(48X),Rd(12X)

Fujitsu-Siemens Storage2
         Disc Type = CDR (A+)             
          Material = Phthalocyanine
           Lead In = 97:26:66
          Lead Out = 79:59:71
  Nominal Capacity = 702.82MB (79m 59s 71f/LBA:359846)
Manufacturer Maybe = CMC Magnetics Corporation
Smart-Burn Speed Limit = Wrt(48X),Rd(12X)

CD-Speed: all green,
KProbe values for a VCD disk (max reading speed is 32x):
Samsung/Plasmon: C1 max/ave = 11 / 1.3
Fujitsu-Siemens (FSI)/CMC: C1 max/ave = 27 / 5.9

Both distributions are essentially flat. These are the first CMC's I've encountered where the C1-count didn't increase towards the end . Both media types are OK, but nothing special- other than that these Samsungs are the classiest looking disks I've ever seen (see Spazmogen's old post).

G

i agree those Samsungs are good looking!




not bad KProbe C1 results either!

They look good AND perform well. Thanks, MediumRare.

They look good, but I wouldn't go as far as saying they perform very well. Those results are on par with some of my 48x CMC disks.

Ahem, I said they performed well, not very well. And they certainly performed better than the 48X Fujitsu-Siemens/CMC discs that MediumRare tested at, I'm assuming, the same time.

I know, but I wouldn't even go as far as saying they worked well. Maybe saying they worked OK.

All I did was add a comment and show my regular appreciation after someone posted a result, but you spoiled it. You win, are you happy now?

No! BTW, the goal wasn't to win, the goal was more to share my opinion. I don't see how I spoiled anything.

Great, you succeeded. Now, with all sincerity, please move on so this thread doesn't become more cluttered with sidetracked discussions. Thank you.

I decided to see what's so bad about the fuji Prodisc cdr's at least this batch seems to burn quite well.
