An information processing apparatus calculates, in a case where an object including at least one of data or metadata related to the data is recorded in a magnetic tape including a first partition in which one or more objects are to be recorded and a second partition in which pieces of the metadata are to be recorded, a second ratio as a ratio between a size of the first partition and a size of the second partition in the magnetic tape by using a first ratio as a ratio between a total size of the objects and a total size of the pieces of the metadata.
