Abstract

PURPOSE:To achieve efficient data processing by enabling streaming modes, through the readout/write in high speed running state with a high speed running system. CONSTITUTION:In addition to systems 1, 2 and 5 normally running a magnetic tape, a high speed running control circuit 3, a high speed running speed reference signal circuit 4, and a speed comparison circuit 6 constituting a high speed running system are provided. Further, a control circut 3 receives a high speed running signal and transmits a control signal to a comparison circuit 6, which compares the control signal with a reference signal from the signal circuit 4 and generates a speed difference signal, and the magnetic tape is run in higher speed than the normal running for readout or write.
