LEADER TAPE AND MAGNETIC TAPE CARTRIDGE EMPLOYING IT

摘要

A leader tape which is less troubled by an increase in dropout caused by denaturing of a drive reel or a leader block part due to long-term storage or traveling at high temperatures, and a magnetic tape cartridge employing it. 1). A leader tape provided with a coating layer containing powder and a binder at least on one side of a support, characterized in that the center line mean roughness (Ra) on at least one side of the leader tape is 10-60 nm, and a frictional coefficient with respect to an Al2O3/TiC member is in a 0.1-0.3 range. 2). A magnetic tape cartridge comprising a single or a plurality of magnetic tape-wound reels rotatably housed in a cartridge case, wherein the leader tape mentioned in 1) is employed as a leader tape being bonded to the forward end of the magnetic tape and being led out to a magnetic recorder/reproducer while leading the magnetic tape.
