Abstract: A method for controlling on magnetic tape the recording of data collected as a physical block comprising a plurality of packets is recorded. When an instruction for reading out the data corresponding to a packet in the physical block is issued from a host unit, the data of the whole of the physical block are read out from the magnetic tape, and stored in a buffer. When a write instruction and data to be recorded are outputted from the host unit at an arbitrary position in the physical block on the magnetic tape, one physical block is reorganized using the data stored in the buffer and the data to be recorded, and this data reorganized as the physical block is recorded on the magnetic tape.
