Paper Abstract

The paper suggests a new scheme of hybrid recording by high refractive index optical waveguide. A recording bit will be determined by thermal gradient and magnetic field gradient, thermal field gradient be used to determine recording track width, and magnetic field gradient will determine recording bit width. In the scheme thermal gradient will be obtained by laser from an optical waveguide. The optical waveguide is flat structure and composed by three materials. The core is high refractive index material, and the clad is low refractive index material. The paper research relationship between track-width and structure of optical waveguide and analyses influence to track density by material refractive index and core thickness of optical waveguide. In theory the scheme can support 500kPTI track density.
