Abstract: PURPOSE:To reduce the required time for retrieval operation considerably by comparing and calculating the information from a tape position arithmetic means and a retrieval mode switching position calculation means and switching the retrieval control means from the ultrahigh speed mode into the PNO-ID retrieval mode. CONSTITUTION:A tape position arithmetic means 6 calculates the position of a tape driven at present with a reel pulse during the retrieval operation continuously, and the position of the tape driven at present is compared with a retrieval mode switching position obtained by a retrieval mode switching position calculation means 12 with comparare arithmetic means 13 while being driven.
