CD-R Quality Tests All CD-R have been burned at 8x speed on an external Liteon 1633SX USB burner.  Testing software is K-Probe 2, reading speed is 16x maximum. Wider images refer to the standard Liteon BSOS firmware, while taller images refer to burns performed with the updated 1653 CS0K / CS0M / CS0P firmwares patched by CodeKing (see CDFreaks.com's Liteon forums for reference). TDK SpeedX Newer firmware, same outstanding results. I really cannot understand why Mitsui Chemicals, maker of great quality media, is classified as C- ! Intenso 74 min (for Audio use) Both C1 and C2 are extremely low also with the newer firmware. A newer firmware, and even that last C2 spike is gone: DataTrack Prodisc Black Traxdata Black I really, really wanted to like this media, as it has been frequently recommended in the audiophile circles as the dye that sounds best. Still, C1/C2 scans are not that good, especially when compared with the Prodisc Black above. Mitsui Golden Dye 74 min Mitsui Golden Dye 80 min Verbatim DataLifePlus Moving to the newer firmware leads to very similar results: Verbatim Pastel (TY) A perfect disk. And what could you expect from the best media maker, Taiyo Yuden? The quality of these CD-Rs is flawless, and they are also quite cheap, with only a minor increase in price compared to Verbatim DataLife. Recommended, this is the media I use for reliable long-term storage. HP (Moser Baer) Moser Baer's disks are one of the very few medias that sometimes had compatibility problems with my Ah! Tjoeb 4000 CD player (the dreadful "Disc not finalized" error message). Primeon (Ritek) Primeon disks are very, very cheap but their quality is not bad at all.
