Abstract
An information processing device includes a generation unit that generates a hierarchy of a group that classifies each piece of data from information about each of a plurality of pieces of data to be recorded, and a control unit that controls recording of the plurality of pieces of data included in a group of the hierarchy at a highest level on a magnetic recording medium in a recording order according to an order from an upper hierarchy to a lower hierarchy, for each group of the hierarchy at the highest level. The magnetic recording medium has a magnetic layer containing a ferromagnetic powder and a binding agent on a non-magnetic support. A difference between spacings Sand Smeasured under pressures of 0.5 atm and 13.5 atm by an optical interference method after n-hexane cleaning on a surface of the magnetic layer is equal to or less than 3.0 nm.
