Multiple optical-recording apparatus using solid immersion lens

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.
