Abstract
PURPOSE: To easily manufacture the high density recording media, by coating the coating liquid including the uniaxial ferromagnetic substance particles having easy magnetization axis orthogonal to the plane is coated via roll pair and by continuous lamination while orientating the particles.
CONSTITUTION: The coating liquid 1 including uniaxial ferro-magnetic substance particles having easy magnetization axis orthogonal to the plane is discontinuously coated on the first roll 3a surface via the gravure roll 4. The magnetic substance particles in the coating liquid 1a discontinuously coated on the roll 3a surface in stripe or pattern are copied on the roll 3b surface while suitably rolled and orientated in the contact with the second roll 3b. The layer 1b including the magnetic substance particles copied on the roll 3b surface with continuous rolling is copied on the band support 5 surface while rolled and orientated to form the continuous magnetic recording media layer 1C and the magnetic recording tape 6 required is obtained.
