3.4 Defining volumes

A volume descriptor set must be defined for the first track of the disk. This is called a volume descriptor track.

Information such as a system identifier and date are recorded in a volume descriptor to identify the volume, but these details are explained in "3.11 Definition of Volume Descriptor Information".
