PURPOSE:To obtain a titled device capable of forming a recording medium having a high orientation rate by providing a holding means of a medium, and a means spraying dry air to the medium, for an unhardened magnetic recording medium running in the orthogonal direction to a magnetic field. CONSTITUTION:A nonmagnetic tape-like substrate 6 on which a coating film layer 5 containing magnetic particles has been provided is made to pass through in the direction as indicated by an arrow 7, in a DC magnetic field formed by an orientation magnet 1 (symbols 2a, 2b denote soft magnetic cores, and 3a, 3b denote solenoids), an easily magnetizing axis is oriented in the running orthogonal direction, and a vertical magnetic recording medium is manufactured. In said device, a nonmagnetic supporting body 4 of channel shape for holding the surface of the substrate 6 which is running, within the range of 90+ or -15 degree against the direction of the magnetic field of the magnet 1, and a nozzle 10 for jetting dry air is provided. Accordingly, when the substrate 6 is passing through in the magnetic field of the magnet 1, the magnetic particles are oriented in a state that the surface of the substrate 6 has been held to a prescirbed angle (for instance, 90 degrees) against the direction of the magnetic field, and subsequently, said orentation state is fixed. |
