Abstract
Provided is a magnetic tape including a data tape, a leader tape joined to the data tape, and a splice tape provided at a joint portion between the data tape and the leader tape, in which a length of the splice tape is 2 mm or more and 10 mm or less, an arithmetic mean peak curvature Spc specified in ISO 25178 on a surface of the magnetic layer of the data tape is 0.30 (1/μm) or more and 0.70 (1/μm) or less, and a standard deviation σ of the Spc in a width direction of the surface of the magnetic layer is 0.15 (1/μm) or less.
