The present disclosure generally relates to tape assembly implementations for magnetic recording devices, such as tape embedded drives (TEDs). In one or more embodiments, one or more of a first reel and/or a second reel is laterally movable relative to a side wall of a casing of the tape assembly. In one or more embodiments, a drive assembly laterally moves the first reel and the second reel substantially simultaneously such that a spindle distance between a first spindle and a second spindle is substantially constant.
