Blank CD discs are generic and there is no distinction between writing audio or data onto them. There are two types of writable blank CD discs, and your Teac is compatible with both:
- CD-R (CD Recordable) which can be burned permanently one time
- CD-RW (CD Rewritable) where the disc can be erased and rewritten
The laser mechanisms typically found in standard CD audio players can read CD-R discs more reliably than CD-RW discs. Therefore it is recommended that you use blank CD-R discs to burn audio CDs.
The RIAA flag that you mentioned would be written by a writer (such as your Teac) as part of the audio data, not something that is already on a blank disc.
