An optical disc is designed to support one of three recording types: read-only (e.g.: CD and CD-ROM), recordable (write-once, e.g. CD-R), or re-recordable (rewritable, e.g. CD-RW). Write-once optical discs commonly have an organic dye recording layer between the substrate and the reflective layer.
An optical disk drive uses a laser to read and write data. A laser in this context means an electromagnetic wave with a very specific wavelength within or near the visible light spectrum.Different types of discs require different wavelengths.omputer software also often comes on one of these discs, so you need an optical drive to install software. Most modern drives allow you to write to an empty disc, so you can create your own music CDs or create a back-up copy of important data.
