A channel input/output unit receives, data read out with a read head and a buffer managing unit receives this data. A header information determining unit determines whether this data includes header information of the old data. If it is determined that this data includes the header information of the old data, a data set determining unit determines whether a data set is extractable from this data. If it is determined that data set is not extractable, a move signal output unit outputs a signal for moving the read head in a direction of the new data.
