摘要： The present invention relates to an apparatus for measuring a slant angle in a solid immersion lens. In a near-field optical data storage head for storing/reading data using a solid immersion lens (SIL), a parallel light is formed within the plane of the solid immersion lens and the slant angle of the parallel light is then measured using the angle measurement principle of the autocollimator in order to measure the slant angle of the solid immersion lens. For this, the present invention includes an optical system for generating the parallel light within the solid immersion lens, and a unit for measuring the slant angle of the solid immersion lens using a location detection unit. An incident light becomes the parallel light by the optical system and the curved face of the solid immersion lens. The reflected light is also focused on the location detection unit. The location detection unit converts the reflection angle of the reflecting light into a location value to calculate the angle value.

摘要： The present invention relates to an optical data recording device using SIL (Solid Immersion Lens) in order to store information with high capacity, and more particularly to the multiple optical-recording apparatus capable of doing multiple information storage and play by forming multiple focus within the SIL. The present invention utilizes the optical technology by multiple source in order to overcome the limit of improving the recording speed and transfer rate due to the mechanical transfer and access, the flying head technology, which was proposed to increase the transfer rate and recording access speed in the near-field recording technology. The present invention can increase the recording speed and transfer rate using optical technology transcending the limit of mechanical transfer and access according to the number of the optical sources and focuses by recording and playing several pits simultaneously after forming multiple optical focus by multiple sources on the recording medium.
