GigaRec AFAIK has its origins in Sanyos "HD-Burn" (http://www.digital-sanyo.com/BURN-Proof/index.html). It never was called anything else than GigaRec by Plextor (AFAIK). I don't know if anyone else ever implemented it and under what name except for Sanyo under the original name in their own drives.

As for Varirate i'm not totally sure, but apparently it describes a technology where only a part of a disc is recorded at at GigaRec-like change in density of Pit/Land for copy-protetion reasons.

If it's true that GigaRec 0.6x & 1.4x are being done away with in favour of settings like 0.9x & 1.1x, I'm all for it! I bet the 1.4x setting has given nothing but problems to those who actually needed to use it. On the other hand, I bet there's many of us that need to burn a bit more than 82 minutes / 720 MB on a CD and could benefit greatly with a GigaRec 1.1x setting. I know I could, as I have several single MP3s that are above 720 MB.

I guess I got a little carried away in my last post. If 1.4x *was* removed for "compatibility reasons" some ingenious hacker may still be able to modify the firmware to allow it in the 716A and / or the new 760.

If Variable-rate GigaRec is possible using Blindwrite, does this mean that GigaRec can be modified to whatever rate the user desires (ex. 0.95x, 1.14x, or a value between 0.6x and 1.4x)?

Chaos2:

I'll bet the reason your 1991 player can only access 3/4 of the GigaRec 1.4x disc is because of the infamous lack of most drives / audio players to read past 99 min 59 sec. I have three standalone DVD players which play a 1.4x disc perfectly up till 99:59 but bomb out after 100 min. On the other hand, I have two laserdisc players: a Sanyo 1989 unit and a 1995 Pioneer 704 player which read 1.4x discs fine, above and beyond even 140 minutes with 1.4x and 99-min CompUSA CDRs.

Wow! That's awesome (about the past 100- and even 140-minute reading in those old players). I think the reason why many drives/CD players can't handle a TOC or playback past 99 min 59 74/75 s is because even 90-minute CDs weren't out yet, let alone 99-minute discs and GigaRec. It actually does make sense, as I doubt anyone really thought that a CD's tolerance can be pushed so far.

PS: Can those 99-minute CD-Rs be overburned, then combine the GigaRec 1.4x with it? That would = 140 to 144 minutes of stereo 44.1 kHz 16-bit audio on a single CD.
