PROBLEM TO BE SOLVED: To provide an optical recording/reproducing head for near-field optical recording/reproducing capable of keeping a floating quantity of an optical lens constant and capable of stably obtaining reproducing signals. SOLUTION: In the floating type optical recording/reproducing head, a mechanism, which controls a relative position between the slider and the optical lens by thermal expansion or a piezoelectric effect of an optical lens supporting member holding the optical lens to the slider or partial thermal expansion of the optical lens, is provided. |
