Except that optical media isn't that durable or reliable. Every DVD or CD I've ever burned has become unreadable after a few years. The inks just don't hold the data for long.
HTL BD-R uses an inorganic phase-change alloy sputtered onto the disc surface. I have media files going back 4 years or so backed up to a bunch of Blu-rays at work, and they've mostly held up pretty well. I recently scanned all of them to see how they were holding up, and out of 300+ discs, 5 had some unreadable areas. They would've been recoverable because I augmented the images before burning with dvdisaster, but it was faster to just mark their contents as not backed up and let them get burned to a newer disc.
LTH BD-R, OTOH, uses the same organic dyes as CD-R and DVD-R, and is just as susceptible to bit rot (though in all honesty, I have plenty of DVD-Rs and CD-Rs kicking around that are still readable.)
Most BD-Rs on the market are HTL. They tend not to be marked as such, but LTH media are. Verbatim seems to be the most prominent of the LTH BD-R brands, though I think I've heard that Taiyo Yuden also produces LTH BD-R. dvdisaster identifies my backup set as a mix of Ritek, Philips, and CMC Magnetics media; they carried a variety of other brands on them (some well-known, some not so much).
If you're not set up for Blu-ray, M-Disc has applied its inorganic recording layer (they describe it as a "rock-like carbon compound") to DVD as well as Blu-ray. You need a drive that can burn them (not just any DVD burner will work), so if you're in the market for a compatible burner, you might as well get one that also handles Blu-ray. Wikipedia says the discs, once burned, are readable in any drive.
