    hi team , i am hunting down High Quality CD-Rs the main focus is a Ultra High Reflective Layer , Taiyo Yuden stink for this task........

    what i need is

    - CD-R common brand availability
    - CD-R Ultra High Reflective Layer
    - Long Lasting
    - 650mb and 700mb sizes a must !

    i posted another thread for DVD-R that have a high Reflective Layer and got excellent results from this forum.

    I don't know why anyone would want an ultra-high reflective layer for any disc. Reflectivity is important but not the most important specification. In the order of reflectivity:

    CD-ROM/DVD-ROM aluminum playback only
    CD-R/DVD+/-R silver The dye reduces the reflectivity, but the dye is specific to a particular wavelength.

    CD-R/DVD+/-R gold less reflectivity than silver; not a problem for CD-R but presents a problem for DVD+/-R

    CD-RW silver
    DVD+/-RW/-RAM silver

    L0 on DVD+/-R hybrid DL discs
    L1 on DVD+/-R silver light passes through 2 dye layers plus the L0 layer

    Taiyo Yuden set the specification for CD-R reflectivity. At the time it was for gold, but today's CD-Rs all use silver/silver alloy that has a higher value of reflectance and is perfectly suitable for today's applications.
