In an optical tape drive system, a movable planarizer subsystem (16) includes a tape planarizer support structure (28) for supporting an optical tape planarizer (10). The support structure (28) is moveable between an operational position and a non - operational position. The movable planarizer subsystem (16) also includes an actuator (36) for moving the support structure (28) and the optical tape planarizer (10) between the operational position and the non - operational position. The operational position of the support structure (28) positions the optical tape planarizer (10) to permit reading/writing of information from/to an optical tape (18) via an optical pickup unit (OPU), and the non - operational position of the support structure (28) positions the optical tape planarizer (10) to permit passage of a tape leader (34) though the tape drive system without damage to the OPU. |
