For those of you who missed it, we have a CeBIT 2004 report on the mainpage which also includes some information on Plextor. Here it is, interesting stuff:
As most of our readers will know, Plextor will introduce the PX-712A DVD recorder. The drive will support 12x P-CAV DVD+R and 8x DVD-R recording speed. Dual layer will not be supported for this drive but Plextor did say that dual layer was interesting. A while back we posted some information about the Sanyo chipset that the Plextor PX-712A will use. The specifications of this chipset are â€˜betterâ€™ (read: supports higher recording speeds) than what the PX-712A will support. Plextor said that this was because they cannot guarantee quality at recording speeds that are too high and thus they choose to support lower speeds, for which they can guarantee the write quality.
Plextor showed us a new version of the PlexTools Professional software which will support DVD error measurement testing using the PX-712A drive. Unfortunately the older Plextor PX-708A drive will not support PI/PO error measurements. The FE/TE and Beta/Jitter tests will also be supported for DVD media. The PlexTools software will have an option with which you can control the drive DVD read speeds. Normally the read speed for DVDs is locked but via the software this can be unlocked. The so-called SpeedRead DVD option will may also be introduced for the PX-708A drive.
PlexTools Professional DVD error measurement test (PI/PO). Notice the PX-712SA (S-ATA) drive in the list of devices.
PlexTools Professional DVD recording transfer rate test. Notice the spikes in the recording speed. Here is where the laser is re-callibrated.
The new PlexTools software can now also give you information on the supported recording speeds for the inserted media. So, when you insert a DVDR disc into your Plextor recorder the PlexTools software will show you at which speeds the media can be written. This information is reported by the recorder itself.
