Abstract: In a tape cassette possessing symmetrically arranged support liners, a compressive force dependent on the tape roll diameter is exerted by the liner and utilized for centering the roll and the tape. Force/diameter relationships, and embodiments of folded liners for achieving individual forces are described. A novel dynamic liner arrangement can be used in any tape cassette possessing high winding speeds and sensitive tapes, with frequently alternating rewind/playback operation.
