Abstract
In magnetic tape recording apparatus a magnetic tape reel is clamped to a spindle apparatus so that vibration between the spindle apparatus and reel is minimized and so that the reel is operable free of contact with a reel container. A magnetic tape reel having a central opening extending from a face of the reel and, within the opening, a plurality of reel projections with inner radial surfaces spaced from the reel face, is clamped to a tubular spindle member by means of a reel clamping member rotatably mounted at the end of the spindle member. The reel clamping member is actuated by a control member which is slidably mounted within the spindle member.
