What is the meaning of ISO 9660, Joliet, and other options in my pre-mastering software?
Logical volume and file structure requirements of ISO 9660, together with conformance to ISO/IEC 10149, are necessary for CD-ROM and CD-R interchange. Improper descriptors, directories, and path tables can result in unpredictable interchange failure, as can improper modes or gaps, high error rates, or out-of-spec parameters. Non-conforming discs may be readable in forgiving systems, but will fail in others. ISO 9660 defines basic requirements for data interchange, and also provides for optional extensions to specific operating systems such as Windows, UNIX, and Macintosh environments. Three ISO 9660 levels control file and directory name lengths, directory depths, and file fragmentation permissions. Each of these elements is managed by pre-mastering software that may not comply with the requirements of ISO 9660 and its extensions. Unpredictable interchange can result. Data CD disc mounting always begins with the drive reading the Primary Volume Descriptor in sector 16. Basic ISO 9660 L
