The data inside the ISO image will be structured according to the file system that was used on the optical disc from which it was created. Other than ISO 9660 media, an ISO image might also contain a UDF (ISO/IEC 13346) file system (commonly used by DVDs and Blu-ray Discs), including the data in its files in binary format, copied exactly as they were stored on the disc.

Optical disc images are uncompressed and do not use a particular container format they are a sector-by-sector copy of the data on an optical disc, stored inside a binary file. And like any other ISO image, it may be written to an optical disc such as CD or DVD.

Software distributed on bootable discs is often available for download in ISO image format. ISO images can be created from optical discs by disk imaging software, or from a collection of files by optical disc authoring software, or from a different disk image file by means of conversion. ISO images are expected to contain the binary image of an optical media file system (usually ISO 9660 and its extensions or UDF), including the data in its files in binary format, copied exactly as they were stored on the disc.

ДЄn optical disc image (or ISO image, from the ISO 9660 file system used with CD-ROM media) is a disk image that contains everything that would be written to an optical disc, disk sector by disc sector, including the optical disc file system.
