    Abstract: In a tape drive apparatus commonly shared by a plurality of host devices coupled to the tape drive apparatus over a host port, access control is provided. Each host device is identified by a host address. The tape drive apparatus comprises a data transfer unit for transferring data between a loaded tape medium and the tape drive apparatus. A command for registering a host address of one of the plurality of host devices in the tape drive apparatus for the purpose of authorising access is received over a management port. A command comprising data to be stored on the tape medium is received from a requesting host device over the host port. The host address of the requesting host device is derived from the command received over the host port. The host address of the requesting host device is verified against the host address registered in the tape drive apparatus to determine whether or not the requesting host device has access authorisation.
