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.]
