ABSTRACT:
Data is recorded over tracks formed on a tape storage medium at a predetermined track pitch selected from a plurality of track pitches. The selected predetermined track pitch is larger than the minimum track pitch among the plurality of track pitches. First absolute addresses of tracks formed by the minimum track pitch are decided. Second absolute addresses of tracks formed by the predetermined track pitch are decided using the first absolute addresses. The data and the second absolute addresses are recorded over the tracks formed by the predetermined track pitch. In decision of the second absolute values, a value of (n-m) high order bits of n bits of each of the second absolute addresses is increased per track formed by the predetermined track pitch, where n is a natural number of two or more and m is another natural number of one or more but smaller than n. The first absolute addresses are also expressed by the n and m bits. Values of the m low order bits of the first absolute addresses are set as values of the m low order bits of the second absolute addresses.
