The CD-ROM itself may contain "weak" sectors to make copying the disc more difficult, and additional data that may be difficult or impossible to copy to a CD-R or disc image, but which the software checks for each time it is run to ensure an original disc and not an unauthorized copy is present in the computer's CD-ROM drive.

However, one could read GD-ROM on CD reader by swapping the disc after reading fake TOC. FADE Creates fake scratches on the disk image which copying programs will automatically try to fix. Instead of alerting the user that the copied disc is detected, the program will play the game in a buggy manner. [4] PlayStation (CD-ROM)

A sector is the primary data structure on a CD-ROM accessible to external software (including the OS).

Among other things, the structural information consists of the sector number, the sector's relative and absolute logical position

A disk image is a snapshot of a storage device's structure and data typically stored in one or more computer files on another storage device. [1] [2]Traditionally, disk images were bit-by-bit copies of every sector on a hard disk often created for digital forensic purposes, but it is now common to only copy allocated data to reduce storage space.
Each issue included software and hardware reviews, as well as a CD containing fonts, video and text files, system updaters, freeware and shareware and demo versions of commercial software. Products were included for both Macintosh and Windows PC. CD-ROM Today was the highest-selling review magazine for both Macintosh and PC users in 1996. [1]
