Figure 8-64 READ POSITION CDB
The READ POSITION command is used to read a position identifier, or SCSI Logical
Block Address. The LOCATE command uses this identifier to position back to this
same logical position, in a high performance fashion.
BT
The Block Type bit indicates how the position is interpreted. Since this device uses the
same logical block address whether this bit is set or not, the setting of BT is ignored.
The logical block address values include all recorded objects: blocks and filemarks.
__________________________Note _____________________________
The drive returns CHECK CONDITION with the Unit Not Ready Sense Key
with the Read Position command if the media is not ready to be accessed.
