Only ×1 writing speed?


#1567

The new Toshiba SD-L912A model made it possible to record HD DVD-R with an x2 transmission.

Toshiba SD-U \T 913A prototypes only seen presented at the fair. They probably have never been available on the market.

What rotation speed and data rate is ×1 or ×2?


#1569

It has one lens for everything.


#1570

Laser is a Toshiba construction with one lens but lasers - diodes are of course 3 (CD \ DVD \ HD DVD)

The write gears are very close to BluRay

It’s been a while, but…

Today’s ultra rare media.

GE Medical Systems DICOM CD-R 74min
Made in Taiwan (?) by CMC Magnetics Corporation
ATIP = 97m 26s 66f
Gold reflective layer, phthalocyanine dye

Here is some rather unusual media. I was fully expecting them to be made by TDK themselves in Japan or USA given the clear TDK branding on the discs but surprisingly they are made by CMC, most likely in Taiwan seeing as though they’re early-ish production. Rather interestingly, these feature a gold reflective layer as opposed to the ubiquitous silver as normally associated with this ATIP. I honestly didn’t know that CMC made gold/phthalocyanine CD-Rs, but there you go!


#1575

How good are these in terms of quality, performance, reflectivity and compatibility and how do the Made in Germany ones compare to these?

Made in Japan 97m26s40f seem quite rare, Made in Germany ones seem more common.


#1576

CDs with integrated burning program, 680MB

And with integrated burning program with password protection



#1577

Not sure. Even though I have quite a few in the collection, my experience with them from a practical sense is limited.

That’s because the European Fujifilm products were generally made by Fuji Magnetics GmBH in Germany whereas the Asian Fujifilm products were generally made by Fuji Photo Film Co., Ltd. in Japan. In North America, Fujifilm CD-Rs were made by either TDK or Taiyo Yuden during those earlier years.

ATIP 97m24s01f (TY)

For fakes the burning quality is good (Pioneer 212 @24x / Optiarc 5240 @ 16x).

Color of Dye is light blue - like at real TY.


#1579

Do you have any idea what is their ATIP code and/or real producer?

If I recall correctly, these were made by CDA Datenträger Albrechts GmbH.


#1580

Made by CDA? I do not want to rule that out, but I do not believe it.
Outer features speak against it, so the light blue Dye (The color of the writing side above is deceptive, its really light blue, like the color of real TY) and the serial numbers.
All my CDA discs had dark blue or steel blue dye.
There is no country of manufacture indicated on the original box (10x10Pack JC).


#1581

Sorry, I meant Customer Pressing Oosterhout.


#1582

That could be more appropriate.


#1583

Xeo CD-R 74 “silver master”
ATIP 97m27s00f
LBA 74m12s00f

“Made in Europe” - by 4M … or CSI ?


#1584

It was most likely made by some small (Italian?) manufacturer using 4M’s technology.


#1585

~ 20 years ago i´d CD-R with same characteristics, branded as “iSi”.
