Support for tape pancakes

A system securing a plurality of tape pancakes includes a compressible baffled core support on which the pancakes can be mounted. An interior rod having a head fits and is received within the baffled core support. A nub on the inside surface of the core support engages a groove on the outside surface of the interior rod to provide a threaded engagement between the interior rod and the core support. Rotation of the interior rod within the core support after the head contacts the end of the core support provides an axial compression load onto the core support to hold together the pancakes. This axial compression also expands the baffles which contact and tighten against the inside of the tape pancake cores and provide a radial force to secure the pancakes in place.
