If an optical drive is titled "DVD+RW," does that mean it's a DVD burner? Or does it mean that it reads DVD's and burns CD-R's? The exact name of the drive is TEAC DVD+RW DV-W58E. I never fully understood all these acronyms. I just know that DVD+/-RW means dual layer, being able to burn and read both CD-R/RW and DVD-R/RW. Thank a lot.
