What software do I use for CD-R/CD-RW software functions?
Sony recommends using the preinstalled SonicStage software's Record function to create any CDs on your VAIO computer,
®
if the specific model you purchased is preconfigured with all necessary components for CD-R and CD-RW capability.
Downloading the optional RealJukebox CD-burning component to create any CDs on your computer may interfere with
normal system operations.
