<p>An optical storage interface apparatus comprises a lens module (LM). The lens module (LM) may comprise, for example, a solid immersion lens for near-field optical readout or near-field optical recording, or both. The lens module (LM) forms a light spot (SP) on an optical information carrier (DSK) in response to a light beam (BO) that is projected on the lens module (LM). A lens actuator (LA) moves the lens module (LM) from a rest position, which is relatively distant from the optical information carrier (DSK), to a read position, which is relatively close to the optical information carrier (DSK). A controller verifies whether the lens module (LM), when moving from the rest position to the read position, has a velocity that is below a velocity threshold or not. If not, the controller causes the lens actuator (LA) to pull back the lens module (LM) with respect to the optical information carrier (DSK).</p> |
