REPORT DENSITY SUPPORT provides information regarding the supported densities for the logical unit be sent to
application client.
MEDIA: The MEDIA bit of ZERO indicates that the drive shall return density support data block for densities
supported by the logical unit for any supported media. The data returned by the drive shall be static if the MEDIA bit
is ZERO. The MEDIA bit of ONE indicates that the drive shall return density support data block for densities
supported by the mounted medium. If the MEDIA bit is ONE and the logical unit is not in the ready state, CHECK
CONDITION status shall be returned. The sense key shall be sent to NOT READY.
The Allocation Length field specifies the maximum number of bytes that the drive may return.
The REPORT DENSITY SUPPORT command returns the REPORT DENSITY SUPPORT header followed by one
DENSITY SUPPORT data block. The Density support data blocks shall be in numerical ascending order of the
primary density code value for each block.
