Leader Tape and Magnetic Tape Cartridge Using the Same

Abstract

An object is to provide a leader tape which suppresses the increase of dropout resulting from imprinting of the drive reel or leader block part due to storage for a long time or running at a high temperature and hardly causes the edge damage of a magnetic tape, and also provide a magnetic tape cartridge using the leader tape. 1) A leader tape comprising a support having provided on at least one surface thereof a coating layer comprising a powder material and a binder, wherein the center line average roughness (Ra) on at least one surface of the leader tape is from 10 to 60 nm and the friction coefficient against an Al2O3/TiC member is from 0.1 to 0.3; and 2) a magnetic tape cartridge including a cartridge case; and a single reel or a plurality of reels, each reel being rotatably housed in the cartridge case and having a magnetic tape wound therearound, in which the magnetic tape has a leader tape of 1), the leader tape being jointed to an leading end of the magnetic tape and drawn out into a magnetic recording and reproducing apparatus while leading the magnetic tape.
