Abstract: [Solving Means] A magnetic recording medium according to an embodiment of the present technology is a tape-shaped magnetic recording medium, including: a magnetic layer including a servo band, a servo signal being recorded on the servo band. An index expressed by Sq×Fact.(p?p)/F0(p?p) is 0.42 or more, Sq being a squareness ratio of the magnetic layer in a perpendicular direction, F0(p?p) being a peak-to-peak value of a first magnetic force gradient strength observed by a magnetic force microscope when a servo signal is saturation-recorded on the magnetic layer, Fact.(p?p) being a peak-to-peak value of a second magnetic force gradient strength for the servo signal recorded on the servo band observed by the magnetic force microscope.

Abstract: A magnetic head and method for making same which can be used for formatting or writing servo tracks or data on a tape. In one example, the magnetic head may include a magnetic thin film layer; at least one gap defined in the magnetic thin film layer; and at least one secondary sub-gap structure within the magnetic thin film layer, the at least one gap positioned proximate the at least one secondary sub-gap structure. Through the use of the secondary sub-gap structure, the gap (i.e. a record gap or channel) can be made thinner than in conventional heads.
