Abstract

PURPOSE:To reduce a coefficient of friction, to suppress slide resistance and also to prevent the abrasion and damage of a disk surface by providing many holes in nonwoven cloth, bonded to a jacket inside surface at right angles to a disk slide surface. CONSTITUTION:In nonwoven cloth 6, many holes 7 are provided at prescribed intervals prependicularly to slide surface 61 of the magnetic disk. This nonwoven cloth 6 bonded to the inside flank of jacket 5 is small in contact area with magnetic disk 4 and, when meeting disk 4 rotating in the direction of arrow A, has its edge part 62 expanded into holes 7, so that this edge part 62 will not come into specially strong contact with disk 4. Therefore, the coefficient of friction is reduced, the slide resistance can be suppressed sufficiently and the abrasion and damage of the disk surface can be prevented.
