The flow due to torsional oscillations of a disk about a steady rotation in an elastico-viscous fluid which is also rotating has been analyzed. The flow is characterized by two circularly polarized waves travelling with different velocities. It is found that the depth of penetration or wave length decreases for and increases for where is the elastic parameter and is the frequency parameter. The unsteady axial velocity at large distance from the disk has a phase lead for and a phase lag for .
