Testing Your CDs and DVDs
The Plextor PX-716UF 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-716UF 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.
To measure read transfer rate response:
1. Place a recorded disc in the PX-716UF. You can use a pre-recorded,
commercially stamped CD or DVD disc; or you can use a recorded
DVD+R/RW disc, DVD-R/RW disc, or CD-R/RW disc.
2. From the PlexTools menu bar, select Read Transfer Rate Test. You
see the Read Transfer Rate test window with a graph for read speeds.
