They are very overpriced media made by either MAM-A or MAM-E with a quite average quality.

Where are you from?
Taiyo Yuden’s CD-Rs are considered to be the best CD-Rs around. If you want gold CD-Rs, you can try Emtec (or Hi-Space) gold CD-Rs made by MPO France. But they are quite hard to find now.

CSI were an owner of the MAM-E and MAM-A which were using CSI’s stampers after they ran out of original Mitsui’s stampers (Mitsui did own the MAM-E and MAM-A before CSI did).

Hello to everybody :slight_smile:

i live in Switzerland, would like to know, where i can buy these cd-r gold
…i’ve search in internet but is really hard to find…
Need a little help.

Thanks.

Merry Christmas to all

Hi there,

The only decent media with any sort of gold reflective layer that I would recommend would be Verbatim UltraLife, Made in UAE by FTI. They actually have a dual reflective layer (gold on top of silver). You get the best of both worlds - high reflectivity and compatibility of silver combined with the longevity of gold.

The quality of MAM-A media cannot be compared to old-school Mitsui.

Hope that helps!

Thanks for help,
i’ve a Tascam and it need a cd-r with low speed write…
i will search for Verbatim.

Thanks

Have a nice Day.

The Verbatim is a 52X product. Older drives (i.e. more than 15 years old) may not perform reliably with this media because the firmware may not have support for it. It is almost impossible to find low-speed media these days, particularly archive-specific media.

Those Verbatim Archival discs are excellent, but as Terminalvelocd has said older drives probably won’t support them very well. They are based on a model of disc which came on to the market around 2002-2003.

How old is your Tascam? (I assume it is a professional model which doesn’t force you to use the special, recording industry taxed, ‘audio’ CD-R.)

For older drives Taiyo Yuden CD-R are probably your best bet, as they have changed very little over the years. The modern high speed version are very similar to the older slow versions. Their ‘Studio Gold’ discs are discontinued, but still available here in the UK - at a price. I would suggest trying a standard silver Taiyo Yuden CD-R first if you have any, if your Tascam doesn’t like that then it won’t like the gold version.

[It is worth mentioning that gold reflective layers have a significant disadvantage, its reflectivity is substantially lower than silver. Verbatim have been very clever with their dual-silver/gold discs. The reflective layer is silver; the gold layer is used as an inert barrier between the silver and the dye. So all else being equal, silver discs have better readability than gold. Gold is chemically inert, so may have better longevity than silver. But there are other points of failure in a disc. And with good quality modern discs the silver reflective layer is well enough protected that it is likely to last as long as the rest of the disc. If your recordings are important and need to be kept for a long time, then the single most important thing you can do to preserve them is extract the audio securely from the recorded audio CD and store it as a file(s) on a data optical disc (CD, DVD or Blu-Ray). Audio CDs don’t have proper error correction or a checksum. Data CDs & others have an additional layer of error correction in the file system which [U]greatly[/U] enhances the chances of being able to read a damaged or degrading disc.]

Hi,
Tascam is CD-RW 5000 and i thing support only til 12x

Still searching…but really hard…quasi impossibile…


#16

Looks like that model dates to around 2000. (Nice piece of kit.) So, unless it had a firmware update, it is unlikely to have specific support for modern Verbatim CD-R. I remember trying some a dozen years ago in a Ricoh 4x SCSI CD-RW (1999 vintage). The results were perfectly readable, but the BLER/C1 average was sky high - a sign that the generic strategy the drive used was not very well suited to those discs.

How well discs perform at a slow writing speed doesn’t really have much (of anything) to do with the discs’ rated speed. What matters is whether or not a drive has a good writing strategy for that disc model at that speed.

I think your best bet is to try some Taiyo Yuden CD-R. They are by far the most compatible current discs with old drives.

The ATIP code of current Taiyo Yuden discs is 97m24s01f (this is the principle piece of information drives use to identify blank CDs). I don’t know when they started using that code (Terminalvelocd probably knows to the exact day ;)), but I think it goes back to at least the late 1990s/8x speed era. To identify the different generations of CD-R they changed the length code instead (the other code drives use to identify discs). Even if your Tascam doesn’t recognise the length code, it should recognise the ATIP code and hopefully produce good results.

The worst case scenario is that a drive will use a generic strategy based on the disc type - the last numeral of the ATIP code. In this case 1=Cyanine, and by far the most popular cyanine CD-R have always been Taiyo Yuden. (Not surprising as they were involved in inventing CD-R discs.)

I should mention that the Verbatim UltraLife CD-Rs made by FTI actually have a TDK ATIP (97m 15s 05f).

Even if your Tascam doesn’t recognise the length code, it should recognise the ATIP code and hopefully produce good results.

ATIP = 97m 24s 01f dates back to 1998. Initially, two variants were produced - 6x 63min and 6x 74min. I believe the first 80min variety was introduced a year or so later.

Ah. That makes a huge difference. :o:flower:

I thought they were still using Verbatim’s AZO dye & 97m34s23f ATIP code, like the original Falcon-made gold/silver archival CD-R.

Do you know when TDK started producing Phthalocyanine discs with the 97m15s05f ATIP code? End of the 1990s?
