I would like to reply to this old post. I have to say that both samhnky I used an Optorite burner for several years. It worked great ans Sanyo's HD-Burn technology, which Optorite includes, with Nero worked great.
Click to read about HD-Burn technology.
I like the Optorite people a lot and they allowed me to trade in my CD burner for their DVD+-R DVD burner, with HD-Burn.
EVentually, it needed repair and I purchased a Lite-On DVD burner and forgot about the HD-Burn technology. On of the reasons I forgot about it was that, it worked on CDs only. In the last year or so, the cost of DVDs has plummeted to be about the same price as a CD. Therefore, I didn't think of the archival CDs that I have that are written in HD-Burn format.
Unfortunately HD-Burn did not become a "standard" that I am sure Sanyo hoped it to be. Therefore I seemingly might be stuck with archival data on HD-Burn CDs that I cannot read.
I just wrote a e-mail to Sanyo's HD-Burn people to see about the possibility of some software/driver that would allow the reading of HD-Burn formated data, so I can recover my archival HD-Burn media.
It really is a great technology and I am not sure that they ever got to the HD-Burn for DVDs. That would really be powerful as the DVD + RL are expensive when compared to the single sided DVDs. It also is really convenient to have less archival media as well as the fact that Nero handled it so well.
If I find out that I can read the my HD-Burn CDs, I will post it.
