摘要： A magnetic recording medium of the present invention is a magnetic recording medium including a non-magnetic substrate; a non-magnetic layer that is formed on one of principal surfaces of the non-magnetic substrate and contains a non-magnetic powder, a binder, and a lubricant; and a magnetic layer that is formed on a principal surface of the non-magnetic layer opposite to the non-magnetic substrate and contains a magnetic powder and a binder. The magnetic powder has an average particle size between 10 nm and 35 nm inclusive. The lubricant is migratable to the magnetic layer and forms a lubricant layer on a surface of the magnetic layer when a pressure is applied to the magnetic layer. When spacing of the surface of the magnetic layer before and after washing the lubricant with n-hexane is measured with a TSA (Tape Spacing Analyzer), the value of the spacing after washing is 3 to 10 nm, and the value of the spacing before washing is 1 to 5 nm smaller than the value of the spacing after washing.

摘要： A magnetic tape of the present invention includes a plurality of data bands in which a data signal can be recorded and servo pattern portions composed of a burst signal. The servo pattern portions are formed at a predetermined interval in a longitudinal direction of the magnetic tape in a plurality of data bands, and positions of the servo pattern portions formed in the respective data bands in the longitudinal direction of the magnetic tape vary. According to such a configuration, a magnetic tape can be provided, which is traced stably by the magnetic head even if the magnetic tape is deformed due to temperature and humidity.
