12.APPENDIX E: Medium Auxiliary Memory Attribute
12-10 SONY AIT-5 drive SDX-1100V series Ver.1.0
Note:
The Formatted Density Code ID 0006h, which is in the Device Common Attribute section and the Medium
Density Code ID 0405h, which is located in the Medium Common Attributes section, will need to be used in some
cases in conjunction in determining the media format.
0406h MEDIUM MANUFACTURE DATE:
This attribute value identifies the date of manufacture of the medium.
The format is YYYYMMDD.
0407h MAM CAPACITY:
This attribute value is the total capacity of the MAM, in bytes, at manufacture time. It
does not indicate the free 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.
0408h MEDIUM TYPE and 0409h MEDIUM TYPE INFORMATION:
These attribute values give information about
non-data media and other types of media. The MEDIUM TYPE INFORMATION attribute is interpreted according to
the type of medium indicated by the MEDIUM TYPE (Table 12-11).
Note:
Depending of the hardware vendor, this attribute may not be hard coded into the MAM at manufacture time.
