Abstract

A leader tape to be spliced in a butting manner to a leading end of a magnetic tape, the leading end being mechanically cut in a tapered shape, wherein the leader tape has a surface roughness RZ (RZ complies with JIS B0601-1994) of 5 μm or less.

Claims (3)

1. A leader tape to be spliced in a butting manner to a leading end of a magnetic tape, a leading end of the leader tape being mechanically cut having a tapered shape, wherein the leader tape has peaks and valleys formed on a surface such that a roughness RZ of the surface is 5 μm or less.

2. A magnetic tape cartridge comprising: the leader tape according to claim 1 ; a single magnetic tape reel; and a magnetic tape whose one end is spliced to the leader tape using a splice and whose other end is wound around the single magnetic tape reel.

3. The leader tape of claim 2 , wherein the peaks of the leader tape stick into the splice thereby enhancing strength of mechanical bonding therebetween.
