The ISO file format is used to make copies of CDs and DVDs. This format is suitable for storing data, file system file attributes, as well as directory structures. A typical copy of a file, from a disc, does not inlcude complete data as the header information is lost. However, an ISO image includes complete data including header information from the disc.
ISO images contain the binary image of the file system as well as the data present on the optical media. Both the file system and data are copied exactly as stored on the disc. In other words, an ISO image is identical to a disc, only without the physical disc.
Once an ISO image is created, do the following to bring the ISO image to a physical disc. To burn a DVD ISO, insert a blank (or rewritable) DVD disc into the burner drive. To burn a Blu Ray ISO, insert a blank Blu Ray (or rewritable) disc into the Blu ray writer.
