ISO 13490
Encyclopedia
ISO/IEC 13490 is the successor to ISO 9660
(level 3), intended to describe the file system
of a CD-ROM
or CD-R
.
ISO 13490 has several improvements over its predecessor. It fully addresses the filename, POSIX
attribute, and multibyte character issues that were not handled by ISO 9660. It is also a more efficient format, permits incremental recording, and permits both the ISO 9660 format and ISO/IEC 13490 format to co-exist on the same media. It also specifies how to use multisession properly.
It is derived from the Frankfurt Group proposal and fully supports orange book
