Techopedia Explains Optical Media

Optical media provides more data capacity and longer media device life than earlier methods of data storage. The data on optical media is stored in a digital form in circular sectors and written, edited and accessed using a laser head (inside an optical media drive). Optical media units are often portable and can easily be transported to different systems and locations. CD, DVD and Blu-ray are currently the most common forms of optical media devices.
