Medium Type Attributes
Medium type attributes are stored in the medium auxiliary memory by the media
manufacturer. All supported medium type attributes have a status of read only.

MEDIUM MANUFACTURER
(ID 0400h): Contains eight bytes of left-aligned ASCII
data identifying the vendor of the media. The medium manufacturer’s vendor
identification is assigned by INCITS.
MEDIUM SERIAL NUMBER
(ID 0401h): Contains the manufacturer’s serial number
for the medium.
MEDIUM LENGTH
(ID 0402h): Specifies the length of the medium in meters. A
value of 0h specifies that the length of the medium is undefined.
MEDIUM WIDTH
(ID 0403h): Specifies the width of the medium supported by this
density. This attribute has a rounded units of tenths of millimeters. The MEDIUM
WIDTH attribute may vary for a given density depending on the mounted medium. A
value of 0h specifies the width of the medium is undefined.
ASSIGNING ORGANIZATION
(ID 0404h): Identifies the organization responsible for
the specifications that define the values in the MEDIUM DENSITY CODE attribute.
MEDIUM DENSITY CODE
(ID 0405h): The media density code. This value is also
returned in the MODE SENSE Data Block Descriptor as described in the MODE
SENSE command section.
MEDIUM MANUFACTURE DATE
(ID 0406h): Contains the date of manufacture of
the medium. The format is YYYYMMDD (i.e., four numeric ASCII characters for the
year followed by two numeric ASCII characters for the month followed by two
numeric ASCII characters for the day with no intervening spaces).
MAM CAPACITY
(ID 0407h): Is the total capacity of the medium auxiliary memory,
in bytes, at manufacture time. It does not indicate the available space of an unused
medium auxiliary memory because some of the medium auxiliary memory space
may be reserved for device-specific use making it inaccessible to the application
client.
