Magnetic recording medium and manufacturing method therefor |
| abstract |
It is an object to provide a magnetic recording medium which is capable of satisfactorily preventing deformation thereof and maintaining an excellent state of contact with a magnetic head, which exhibits satisfactory durability and an excellent recording/reproducing characteristic and which is able to realize a high linear recording density. A magnetic recording medium incorporates a non-magnetic support member in the form of a biaxially-oriented polyethylene terephthalate film and magnetic layers formed on the non-magnetic support member and containing ferromagnetic powder and a polymer material. The non-magnetic support member is structured such that difference DELTAn1 between a refractive index of a first main surface and that of a second main surface is 1x10-3 or smaller. It is preferable that the thickness of the non-magnetic support member is 30 mum or greater, a coefficient of thermal contraction at 80° C. is 0.1% or lower and the difference DELTAn2 between a maximum value and a minimum value of the refractive index in each main surface is 15x10-3 or smaller. It is preferable that magnetic layers contain thermosetting polyisocyanate. |
