Owing to the conventional optical pick-up head has diffraction limit in data storage. In order to overcome the diffraction limit, the research focuses on the optical data storage system by near-field recording (NFR). In NFR pick-up head, the SIL/SSIL and aperture are key components to overcome the diffraction limit. According to the previous research, combining the SIL/SSIL and aperture together in NFR pick-up head can obtain better optical resolution and performance. But the misalignment between the SIL/SSIL and aperture always occurred in assembling or bonding step. Hence the research here brings up the self-alignment technique to overcome the misalignment problem. The glass substrate is chosen for self-alignment technique, which is based on the backside exposure. By backside exposure step, the SIL/SSIL and aperture will be aligned precisely. Furthermore, a new integration structure of NFR pick-up head combining SIL, aperture, and microcoil is proposed. The fabrication process is based on Micro Electro Mechanical System (MEMS) and UV-LIGA technologies. This fabrication process is a batch process without assembling or bonding step. Comparing with the conventional fabrication process, the low cost and easy process step can be obtained in this process.
