| titleOfInvention | Magnetic recording medium |
| abstract | A magnetic recording medium comprises a non-magnetic substrate and a metal thin film magnetic layer formed by an oblique evaporating method on the substrate, the non-magnetic substrate being an aromatic polyamide film. The film has a thickness of 3.0 μm to 6.0 μm, has a Young's modulus in the transverse direction of 16000 MPa to 18000 MPa, and has a thermal contraction coefficient (in the transverse direction; 180° C. for 30 minutes) of 0.7% to 1.3%. With this structure, it has been found that the thermal deformation (cupping) after the thin film is formed can be prevented to improve head touch and the electromagnetic conversion properties. |
