What is a
DVD+-RW Drive?
A DVD+-RW Drive (also
called a DVDRW, DVD Burner, or DVD Writer) is a combination of a DVD+RW
and a DVD-RW. DVD+-RWs can be used for reading CDs, writing and/or
rewriting to CDs, and writing and/or re-writing to DVDs. The DVD+-RW
(plus and minus) drive is capable of writing to both DVD+R/RW disks and
DVD-R/RW disks. DVD+-RWs also function as CD Burners and DVD Readers so
they can be used to write to CDs and can also play DVD movies on your
computer.
What does the format for DVD+-RW
Speed ratings mean?
A DVDRW speed rating is typically shown in the format of DVD
Write Speed x. The X values are representative of multiples of 1.32
MB/s. For example, a 16 x DVD+-RW drive can write DVDs at 16x = 21.2
MB/s. DVD Writers are also usually rated for DVD Read and CD Read/Write
speeds.
What is the difference between DVD+R and DVD-R?
DVD+R and DVD-R are two
incompatible formats that define differing writing procedures for
slightly different media types. It is important to realize that if you
purchase a DVD-R writer you will not be able to write to DVD+R media.
Conversely, if you purchase a DVD+R writer you will not be able to write
to DVD-R media. Most modern-day DVD writers are dual-format capable (ie-
a DVD+/-RW drive) and they can write to both DVD+R and DVD-R media. If
possible, it is better to purchase a Dual-Format capable drive to ensure
that you will be able to write to both media types. |
