Read/Write Command Processing: The read/write function is used for com-
munication when the Data Carrier is motionless. Therefore, it must be con-
firmed that the Data Carrier is at a specified position, i.e., in the
communication area of the R/W Head. If the Data Carrier is missing, the ID
Controller returns a response to that effect.
