12.4.4. Standard Medium Type Attributes
Medium type attributes (Table 12-10) are hard coded into the medium auxiliary memory at manufacture time. All
supported medium type attribute will have a status of read only.

0400h MEDIUM MANUFACTURER: This attribute value contains eight bytes of ACSII data identifying the vendor
of the media.
Note: It is intended that the MEDIUM MANUFACTURER attribute provide a unique vendor identification of the
manufacturer of the media. In the absence of a formal registration procedure, T10 maintains a list of known vendor
identification codes in use. Vendors are requested to voluntarily submit their identification codes to T10 to prevent
duplication of codes.
0402h MEDIUM LENGTH: This attribute value specifies the length of the medium in meters. A value of 00h
specifies that the length of the medium is undefined.
0403h MEDIUM WIDTH: This attribute value specifies the width of the medium supported by this density. This field
has units of tenths of millimeters. The value in this field will be rounded up if the fractional value of the actual value
is greater than or equal to 0.5. The MEDIUM WIDTH field may vary for a given density depending on the mounted
medium. A value of 00h specifies the width of the medium is undefined.
0404h ASSIGNING ORGANIZATION: This attribute value identifies the organization responsible for the
specifications defining the values in the MEDIUM DENSITY CODE attribute. The ASSIGNING ORGANIZATION
field willl contain a value listed in the vendor identification list.
The MEDIUM SERIAL NUMBER identifies the manufacturer’s serial number for the medium.
The MEDIUM DENSITY CODE is the same numeric DENSITY CODE as reported in the SCSI Mode Block
Descriptor.
