Abstract
A leader tape where an non-magnetic under layer that contains a powder and a binder and a magnetic upper layer are sequentially laminated on at least one face of a support, in which F5 values of the support in a machine direction (MD) and in a transverse direction (TD) are from 80 to 120 MPa respectively, the F5 value in MD is larger than that in TD, and a difference between the F5 value in MD and that in TD is 15 MPa or less.
Claims9
A leader tape comprising:
- a support;
- a non-magnetic under layer that contains a powder and a binder;
- and a magnetic upper layer in this order on at least one face of the support,
- wherein the support has a first F5 value in a machine direction and a second F5 value in a transverse direction,
- the first F5 value and the second F5 value are from 80 to 120 MPa,
- the first F5 value is larger than the second F5 value, and
- a difference between the first F5 value and the second F5 value is in a range of 2 MPa to 15 MPa.
