The file system primarily used for discs, such as CDs and DVDs, is ISO 9660. This standard was specifically designed for optical disc media to ensure compatibility across different operating systems. Its primary focus is on facilitating the storage and retrieval of data on these discs, allowing the burning of files in a format that various systems can read.

ISO 9660 allows for the proper organization of files and directories on optical media, and it can be supplemented with extensions, like Joliet or Rock Ridge, to provide additional features or support for longer file names and permissions. This makes it suitable for the requirements of these types of media, especially in terms of portability and broad compatibility.

Core Storage, Unix File System (UFS), and New Technology File System (NTFS) cater to different storage environments or devices and are not optimized for optical disc formats. Hence, ISO 9660 stands out as the standard file system specifically tailored for the characteristics of CDs and DVDs.
