When Raw Disk Image type is not mentioned explicitly in this guide, we are referring to the Backup Disk Image. Another file format supported is ISO image. ISO images are used to store a copy of CD/DVD/Blue-ray disc in a file and stand apart from actual disk images.
As you learned in my All About CD-R and CD-RW Daily Drill Down, CD-ROM data is stored in patterns of pitted and unpitted (âlandâ) areas on a disc. DVD data is stored the same way, except the pits are much smaller and closer together. Thatâs why CD-ROMs top out at about 650-700 MB of data, while DVDs can hold multiple gigabytes of data. Since the pits are more tightly written on a DVD disc, the mechanism in the drive for reading them also has to be finer and more precise.
