摘要：
A method for magnetic orientation of a magnetic recording medium uses Meissner effect of a superconductor (100) and means (3) generating a magnetic flux, and a magnetic recording medium (2) is supported between the superconductor (100) and the magnetic flux generating means (3). Magnetic particles of plate hexagonal barium ferrite in the magnetic coating of the magnetic recording medium (2) are allowed to orient in the longitudinal direction thereof so that the magnetic recording medium (2) has a magnetic orientation in this direction.
