Abstract
Official abstract text for this publication.
The magnetic tape has on one surface of a nonmagnetic support a magnetic layer containing ferromagnetic powder and binder, and on the other surface of the nonmagnetic support, a backcoat layer containing nonmagnetic powder and binder, wherein the total thickness of the magnetic tape is less than or equal to 4.80 μm, the backcoat layer contains one or more components selected from the group consisting of a fatty acid and a fatty acid amide, and a C—H derived carbon, C, concentration calculated from a C—H peak area ratio in a C1s spectrum obtained by X-ray photoelectron spectroscopy conducted at a photoelectron take-off angle of 10 degrees on a surface on the backcoat layer side of the magnetic tape ranges from 35 to 60 atom %.
First claim
Opening claim text (preview).
What is claimed is: 1. A magnetic tape, which comprises on one surface of a nonmagnetic support a magnetic layer comprising ferromagnetic powder and binder, and on the other surface of the nonmagnetic support, a backcoat layer comprising nonmagnetic powder and binder, wherein a total thickness of the magnetic tape is less than or equal to 4.80 μm, the backcoat layer comprises one or more components selected from the group consisting of a fatty acid and a fatty acid amide, and…
