Limiting Disc Deflection

A method comprising:

• obtaining an actuator for a data storage device having a data storage disc that is rotatable around a first axis, the actuator being operably rotatable around a second axis to position a data transfer member between an innermost radial location of the data storage disc and an outermost radial storage location of the data storage disc, and a snubber supported by the actuator and having a distal edge configured, in relation to a reference plane including the first axis and the second axis when the actuator is rotated to position the data transfer member at the innermost radial location, on one side of the reference plane as being concave to the second axis and on the other side of the reference plane as being non-concave to the second axis;
• rotating the actuator to move the data transfer member to a first radial storage location where only the distal edge on the one side of the reference plane is within the annulus;
• and
• rotating the actuator to move the data transfer member to a second radial storage location where the distal edge on the other side of the reference plane is within the annulus.
