Dear All,
Many brands of CD-R are now being made by one manufacturer ie Moser Baer in Noida / Greater Noida.
To find out the manufacturer of your CD-R, run one of the following software, which will tell you the factory at which it was made:
1. CDR Identifier
2. CDR ATIP reader
You can google these to find out where they are available.
Further, as regards CD-R quality, there are only two parameters, that is:
1. Readability on all manner of readers (players)
2. Life
Being digital media, CD-R disks will simply record a series of zeros and ones in digital format. It is up to the player to convert it to analog sound. There is no way that certain CD-R disks will sound "warm" or otherwise, or that any method of digital recording will introduce any colour or warmth to the digital music recording. The bits and bytes of the original will be faithfully copied to the new media, or you will get an error, and the disk will be useless.
My profession requires me to buy CD-R media by the tens of thousands. Naturally, quality is critical, since they are being used to distribute critical information. We find that the Sony media is among the best available. It is being manufactured at the newest plant of Moser Baer (they have 5 or 6 manufacturing lines in the Noida / Greater Noida region alone). The quality control is being performed by both MB and Sony personnel, so the results are quite good. Expect a life of about 10 years, if the disks are handled well.
Also, the quality of CD-R disks has consistently improved over the years. Almost any halfway decent brand available today is much better than the best available even 5 years ago. (I've being buying and recording CD-Rs in bulk since the last 15 years, although for data, not music).
Yes, Taiyo Yuden is the originator of the CD-R. Other manufacturers with original chemical formulations are Mitsubishi / Verbatim (blue dye) and Mitsui. Maybe some more too. But MB / Sony is now perhaps one of the best. We have stopped looking for alternatives anymore for our work.
Hope that helps.
