The rarest/most obscure recordable medium



Wow, do you really burn so often Audio-CDs?


The JVC CD-R from Taiyo Yuden with the CD-Audio tag is a real treasure today.
I have several stationary audio recorders for which it is very difficult to buy good CD-R Audio media.


You´re right, no doubt

have fun with it :slight_smile:

I remember 1999 Axel Hucht made a little box for Philips and Marantz CD-records to make the use of standard CD-Rs possible.

For some Pioneer there is still such things available (or at least listed)


LiteOn CD-R 700MB R80S Professional



LiteOn CD-RW74 650MB Professional



4×-12× :0


I managed to get another copy of Samsung SH-S182D, this time the unit seems to be healthy, older FW SB03 onboard , and it also writes DVD-R (A) without a problem. However the scans and compatibility is still questionable.

Details HERE.

It would really be nice to have someone to burn these discs on proper drive in order to see if standard drives would read it without any issues (as advertised by Pioneer).


i burned some DVD-R (A) @ Pioneer S-201.
There is no problem to read this disks by other Drives.


Did you publish some scans of those?


MCC 00R 200:


MID: PVC (orig. Pioneer):


Thank you, not really great scans, I had one Verbatim DVD-R 2x, MCC 00RG200 burned with Toshiba SD-R5002 in 2004 scanned 2017 with somewhat smoother graph.


MCC 00RG200 is DVD-R for General - that’s another topic.


Looks like Z-CLV.


Today’s ultra rare media.

Princo PRR-C74
Made in Taiwan by Princo Corporation
ATIP = 97m 27s 28f
Gold reflective layer, cyanine dye

With help from oldburny, I was able to purchase 40 pieces of this rare first-generation Princo CD-R media. Many of you would not have ever seen a gold-sputtered Princo before. Interestingly enough, the batch that I received is unbranded. Other batches with exactly the same product SKU have Princo branding on the label side of the disc. It is difficult to see but the recording side, while it appears gold in the photo, is actually slightly on the blue side, obviously with the same light blue cyanine dye as Princo’s later silver-sputtered products.


That´s true, I only know the silver/green dye of Princo CD-R


Looks like Gold/Gold


Hence why I said that it’s hard to see the blue in the photo. It’s not quite like a true gold/gold CD-R.

Another example:-


Verbatim HD DVD-R 15GB



HD-DVD :heart:
Good old times.
