driver, come with the operating system.

DVD+RW

The DVD+RW is a slightly different rewritable DVD format, backed by a group of companies

 

known as the DVD+RW Consortium, which includes Sony. Its advantages include high-

 

compatibility, high capacity and easy-to-use functionality. Like the DVD-RW, it can be

 

rewritten about 1,000 times. However, a DVD+RW drive writes at a higher speed than a DVD-

 

RW drive.
