A Volume Descriptor Set shall be a sequence of volume descriptors recorded in consecutively numbered Logical
Sectors starting with the Logical Sector Number 16. Each successive Volume Descriptor shall be recorded in the
Logical Sector with the next higher Logical Sector Number than that of the Logical Sector in which the previous
Volume Descriptor is recorded. The sequence shall consist of two or more volume descriptors consecutively
recorded as follows.
The Primary Volume Descriptor shall describe the Volume Space, and identify the attributes of the volume,
the locations of a Root Directory and of a group of Path Tables, and the number of volumes in the Volume
Set.
once.
A Supplementary Volume Descriptor shall describe the Volume Space, and identify the attributes of the
volume, the locations of a Root Directory and a group of Path Tables, and the number of volumes in the
Volume Set. It shall also identify the coded graphic character sets used within selected fields of this
descriptor, and of the fields in associated File Descriptors, Directory Descriptors and Path Tables.
A Volume Partition Descriptor shall identify a Volume Partition within the Volume Space, its position and
size, and its attributes.
A Boot Record shall contain information which may be used to achieve a specific state in a receiving system
or an application program.
