CD-Rewritable means that you can use the disc more than once and that the contents of the disc can be erased and rewritten. Philips CD-RW discs can be rewritten a minimum 1,000 times.
CD-RW discs are ideal for anyone who wants to store and rewrite data or images. CD-RW is ideal for applications such as personal data storage, multimedia presentations, digital image storage (including digital photography), temporary storage of internet downloads, back-up, archiving, prepress and software development. If something is not exactly right, just rewrite that portion or the entire disc. Simple!
