According to Akiba PC Hotline, the Plextor PX-760A is out in Japan:

Only 15,800 yen ($135US) too.

Hello!

Plextor disappointed me with their last drives, hope this one is better

14min for 10x DVD+RDL doesn't seem that fast.... I think some drives are already getting 15min or so with 8x

It looks like YSS has bought 3 of them:

So the usual tests by YSS will be coming soon ...




There are also some tests of this PX-760A already published here
[with little translations into english]:
http://dvd-r.jpn.org/PX-760A/index.html

There are also on this wepage detailed photos of the internal boards of both following drives:
PX-760A:
http://dvd-r.jpn.org/PX-760A/board.jpg
PX-755A:
http://dvd-r.jpn.org/PX-755A/board.jpg
Looking carefully at these pics you can see that the "strange wiring" present in the PX-755A has beeen completely removed from the new PX-760A.
For the rest the 2 board look the same (to me at least).
The main chipset seems to be the same in both drives: a Sanyo LC 897496K


So my question is to the experts is:
Why was this wiring which realy looks like "glued on top of the board"
present in the PX-755A ??
Is it in order to prevent:
- the crossflashing 755-->760
- the use of PxScan
- or for some other reason ?

PC Watch also has a few screenshots:

http://pc.watch.impress.co.jp/docs/2006 ... lextor.htm

It looks like they had problems getting the drive to write to DVD+R DL media at 10x.

tsk tsk tsk...
should've adjusted the vertical scale in CDSpeed

YSS has started publishing his tests of the Plextor PX-760A
He has 4 drives !


At the moment there are 9 pages you can access to from this link:
http://homepage2.nifty.com/yss/px760a/px760a_top.htm

For these tests he uses the firmware 1.00 and a mysterious 1.01 (I did not check all graphs !)


And there is a special page
with hardware comparisons between PX-760A and PX-755A:
http://homepage2.nifty.com/yss/px760a/px760a_bunkai.htm[/url]
On this page there are also photos of the PUH's ...



Regarding the boards of both drives the photos YSS links to
show the same thing I posted before:
the strange wiring present in the PX-755A has disappeared fromt he PX-760A:
Board PX-760:

board PX-755:

Could somebody tell us if this other comparison that YSS makes here:
http://homepage2.nifty.com/yss/px760a/px760a_bunkai.htm

between the 2 boards is important or not ??

Detailed photo of the strange wiring present
on the PX-755A board:

IF your brave desolder the wires and find out, otherwise boards look the same to me.

well, the PX-755 is probably just all the PX-760 units that couldn't work properly at top speed... so I wouldn't recommend pulling the wires out, even if it DOES lead to having a PX-760, the results will probably be bad.

Probably right, but if it's non destructive you could just resolder them in place if it didn't work out.

That kind of wiring is somewhat common on 'first runs' of hardware to correct IC layout flaws or the like. (well, by somewhat common, I mean IF a major problem slipped through all the other QA tests and they had a ton they either had to destroy, or manually fix, they will manually fix this way)

I seriously doubt if you did anything to those wires, you'd get anything beyond a non-functional device. Being newer, the 760 just has gotten a 'corrected' board that has the connections properly embedded in the circuitry.

That's a pretty big IF.... and on expensive hardware too!

Very true, and neither of us own one so we'll probably never get to test the theory. IF it was cheap enough and I had acces I'd give it a shot but as you said expensive gear to be just hacking away at. I dont mind killing something I only paid 40 or 50 for...

thiaNine already tried, and it wasn't pretty: http://dvd-r.jpn.org/PX-760A/index2.html#4

Yes, but did it come back when he resoldered the wires or did he try? So anyways looks like a bad idea, you know somebody would try it...
