Advantages of Buffer Underrun Proof Technology
The PlexWriter 40/12/40A incorporates Buffer Underrun Proof Technology
which guarantees that you can write discs at high speed, and still use your computer
for other tasks while you’re writing.
To prevent the interruption of data during writing, every CD-R/RW drive has a
buffer, a memory chip that acts as a kind of “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, or if you use other applications (like surfing the Internet or playing
games or watching movies) while writing.
Buffer Underrun Proof Technology compensates for any interruption in data flow to
the disc. It “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.
Buffer Underrun Proof Technology in your PlexWriter 40/12/40A means you can
safely use your computer for other things while you’re writing to a CD-R or CD-RW
disc. It lets you multitask freely and easily, and lets 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.
Being able to adjust the laser power during the recording process can have some
definite advantages. For instance, depending on the capabilities of your specific
audio equipment, you may be able to change the sound quality of your recordings to
suit the equipment. Or you may be able to correct compatibility problems that occur
when playing discs on certain audio players.
How the Default VariRec Setting Is Determined
In most cases you don’t have to worry about setting VariRec. The setting is 0 (zero)
by default, and this usually works best. This default setting is determined by a
combination of steps:
1. First, we test many types of CD-R and CD-RW media in our factory to determine
the best write strategy (laser power and other factors) for that media.
2. We include a table of the tested media and their write strategy in your drive’s
firmware. (This table is updated when you update your drive by downloading
new firmware from the Plextor web site.)
