Abstract
Provided is a magnetic tape apparatus. In a case where a maximum value of an absolute value of a difference between a servo band interval obtained before the following storage and a servo band interval obtained after the storage of N cycles, in which a predetermined storage is set as one cycle, is denoted by A, and a medium life is equal to or longer than 5 years, which is calculated by a linear function of A and a logarithm logT of T derived from a value of A and a value of the logarithm logT of a total storage time T of the storage of the N cycles, each of which is obtained by setting N as 1, 2, 3, 4, or 5. The medium life is T, in a case where A satisfies Expression a: A=1.5−B+C.
