CONSTITUTION:The magnetic recording liquid (magnetic paint) 12 is coated on the base material 11 made of a synthetic resin and thereafter the base material is passed through an orienting device 13 provided with an introducing port 13b on one side intersecting orthogonally with the winding center line 14 of a solenoid 13a wound to a flat annular shape and a delivery port 13c on the other side before drying by which the coating is subjected to inplane orientation in the direction perpendicular to the travelling direction of a magnetic tape A. The magnetic paint is so dried by a method for feeding hot wind through an aperture 15 of the solenoid 13a or other method so that the orientation can be fixed before the passage of said liquid through the solenoid 13a. The magnetic paint is further dried if the drying is not enough after the emergence from the outlet 13c. The gap direction of a magnetic head 16 to be used for recording and reproduction of such tape A is made the same in the direction perpendicular to the traveling direction of the tape A, i.e, the orienting direction of the magnetic layer. The increase in the density is thus made possible even if acicular uniaxed magnetic particles are used.
