Advantages of BURN-Proof Technology
The PlexWriter 40/12/40U incorporates
BURN-Proof (Buffer Under-Run Proof)
technology, which guarantees that you can
write discs at high speed, and still use your computer for other tasks while you’re
writing.
The Problem: When you use a CD Recordable or CD ReWritable drive to write to a
CD-R or CD-RW disc, the disc needs a constant, steady flow of data to make a
successful write. If this flow is interrupted, you wind up with a disc that is unusable.
You’ve just created a coaster for your table!
To prevent the interruption of data, every CD-R/RW drive has a buffer, a memory
chip that acts as a kind “holding area.” (Typically, the buffer size is 2 MB or 4 MB.)
However, this buffer can be emptied quickly when you write at high speeds. It can
also be emptied if you use other applications (like surfing the Internet or playing
games or watching movies) while writing; or if your source drive cannot read data
fast enough because of its read ability or because the source disc is poor quality and
read errors slow down the data streaming. Any of these factors can produce what is
known as “buffer underrun error.” Simply put, the buffer is drained of data, the flow
to the disc is interrupted—and you wind up with a useless disc.
The Solution—BURN-Proof: This revolutionary technology compensates for any
interruption in data flow to the disc. BURN-Proof technology “remembers” where
writing stopped on the disc when the data flow was interrupted, then restarts writing
in the same place once the data is available again. The result is that your disc is
written successfully.
What BURN-Proof Means to You: BURN-Proof technology in your
PlexWriter 40/12/40U means you can safely use your computer for other things
while you’re writing to a CD-R or CD-RW disc. It reduces the dreaded “coaster
effect,” and lets you multitask freely and easily without bringing the burn to a
screeching halt. All of this is done seamlessly, so you successfully create CDs on the
first attempt.
Advantages of VariRec Technology
This drive is equipped with VariRec (Variable Recording) technology, a feature
offered by Plextor that allows you to manually adjust the drive's laser power during
the audio recording process.
NOTE: In order for you to actually perform the adjustment, VariRec must be
supported by the recording software you’re using.
