Magnetic tape cartridge

Abstract

A magnetic tape cartridge is equipped with a cartridge case in which a single reel with magnetic tape wound on the outer periphery of a reel hub is rotatably housed. The cartridge is further equipped with a locking member, and a plurality of ribs extending in the axial direction and formed in the inner periphery of the reel hub. The locking member is provided within the reel hub so that it is movable between a locking position and an unlocking position in the axial direction of the reel. The locking member locks the reel to restrain rotation of the reel when not being used. A first radial clearance between the locking member and the ribs at the locking position is set to a value smaller than a second radial clearance between the locking member and the ribs at the unlocking position.
