摘要：
A leader tape has, on at least one face of a support, a coating layer that contains a powder and a binder, which is characterized in that the center line average roughness (Ra) of at least one face of the leader tape is from 10 to 60 nm, the leader tape is used in a magnetic recording and reproduction device where the line recording density is at least 100 kfci, and the difference between the recording track width and the reproduction track width is from 0 to 16 μm.
