Magnetic recording tape

摘要

In a magnetic recording tape having a total thickness of 4.0 to 14.5 microns, the base thickness to magnetic layer thickness ratio is from 2:3 to 3:2, the base Young's modulus to magnetic layer Young's modulus ratio is from 1:2 to 2:1 and the tensile strength at 0.5% elongation is 2ROOT d/16 Kg or more to the total thickness d (micron).
