  Raw Disk Image
Disk image files contain all of the data stored on the source drive including not only its files and folders but also its boot sector, file allocation tables or MFT (if applicable), volume attributes, directory forks, free space, and slack space.
A disk image is not a collection of files or folders but is an exact duplicate of the raw data of the original disk, sector by sector, in the form of a file.
Since disk images contain the raw disk data, it is possible to create an image of a disk, even if it is written in an unknown format or even under an unknown operating system.

 disk image - Debian Wiki
The image is saved as a file, which for a full CD or system disk may be quite large (~10 MB to several GB).
The iso image file is a digital copy of CD contents made this way: the ripper searches for the sectors of the CD that have been used, say 251,000 for instance (there are 330,000 sectors on a 74 min CD and 360,000 sectors on a 80 min CD).
A common use of disk images is for remote distribution of software such as Linux distributions: installation floppy disks or CD-ROMs can be recorded as disk image files, transferred over the Internet, and the contents of the original disk(s) duplicated exactly by end users with their own floppy or CD-R drives.

The phase is the fraction of the area of the disk that appears illuminated by the Sun.

 Atari Disk Image FAQ
Because Atari disk drives are soft sectored, and do not use the timing hole of the diskette, its possible to cut an extra write-protect notch into a disk, flip it over, and record again on the other side.
A real Atari disk is a complex mess of adhesive magnetic stuff, made sense of by a dedicated floppy disk controller and then made useable by a computer in the disk drive.
An ATR disk image contains 16 bytes of data that identify it as an Atari disk image, and the remainder is every byte of useable data off the original diskette, stored in the original order it was stored on the disk.

 What is a disk image? - Knowledge Base
A disk image is a file that contains the file structure and contents of a storage device such as a CD-ROM, DVD, or hard drive partition.
On some systems (e.g., all versions of Mac OS X) it is possible to mount a disk image, allowing you to access its contents as if it were a normal (though typically read-only) volume.
There are many different disk image formats, and with the exception of those that are self-mounting, you will most likely need a separate utility to view and copy their contents or create new images.
