Method in order to designate optical tape drive movable levelling device subsystem, and the damage for optical pickup unit as minimum

摘要

In the optical tape drive system, movable levelling device subsystem (16) the optical tape levelling device (10) the tape levelling device support structure (28) it includes for supporting. The support structure (28) it is movement possible in with operating station and inoperative position. Movable levelling device subsystem (16), the support structure (28) and the optical tape levelling device (10) the actuator in order to make move (36) it includes furthermore, in with operating station and inoperative position. The support structure (28) as for operating station, optical pickup unit (OPU) through, the optical tape (18) in order to make the read-out of the information in/entry possible, the optical tape levelling device (10) it positions, the support structure (28) inoperative position positions without the damage for OPU in order the tape reader which minds the tape drive system (34) to make passing possible, the optical tape levelling device (10).
