68 PX-716 Installation and Users Manual
• A disc recorded with GigaRec is playable in all Plextor PX-716
drives. However, because GigaRec is out of the limits for Orange
Book and Red Book recording, the recorded disc many not be
playable in all CD players.
• The PX-716 also supports “overburn,” which is different from
GigaRec. When you overburn a disc, the drive reads the disc’s
information, then writes to the disc vendor’s stated maximum
capacity and a little beyond. Overburn provides smaller increases in
disc capacity than are capable with GigaRec.
Testing Your CDs and DVDs
The Plextor PX-716 achieves high-quality recording on virtually any
media. To confirm operation, you can use the PlexTools Professional
software to measure and display characteristics of the drive and media
you’re using. You can also check the operation of the drive’s laser.
Among the measurements and tests available are:
• Read transfer rate (for CD and DVD)
• Write transfer rate (for CD and DVD)
• C1/C2/CU errors (for CD)
• Laser tracking and focus errors (for CD and DVD)
• Beta and jitter (for CD and DVD)
• PI and PO errors (for DVD)
• TA (time analyzer)
This section illustrates how to perform some of these measurements
with PlexTools Professional.
Measuring Read Transfer Rate
The Read Transfer Rate selection lets you test the transfer rate of data
read from a disc. This function reports the read response of the Plextor
PX-716 drive, and is for use on a CD or DVD that contains content—
that is, a commercial pressed disc, or a disc recorded on a DVD or CD
burner.
