ISO/IEC 13490 (also known as ECMA-168) 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 media.
ISO 13490 define a rule for operating systems as to how to read a multiple-session ISO 9660 volume from a CD-R. Instead of looking for the volume descriptor at offset 32,768 (sector number 16 on a CD) from the start of the disc (which would be the default behavior in ISO 9660), programs accessing the disc should start reading from the 16th sector in the first track of the latest session. Sector numbers form a contiguous sequence starting at the first session, and continue over added sessions and their gaps.
Off with your head
Dance 'til you're dead
Heads will roll, heads will roll
Heads will roll on the floor
Glitter on the wet streets
Silver over everything
The river's all wet
You're all cold
Dripping with alchemy
Shiver stop shivering
The glitter's all wet
You're all chrome
The men cry out, the girls cry out
The men cry out, the girls cry out
The men cry out, oh no
The men cry out, the girls cry out
The men cry out, the girls cry out
The men cry out, oh no
Oh, oh, oh, oh
Off, off with your head
Dance, dance 'til you're dead
Heads will roll, heads will roll
Heads will roll on the floor
Looking glass, take the past
Shut your eyes, you realize
Looking glass, take the past
Shut your eyes, you realize
Glitter on the wet streets
Silver over everything
The glitter's all wet
You're all chrome, you're all chrome
Oh, oh, oh
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
Dance, dance, dance 'til you're dead
Off, off, off with your head
