Abstract
The paper introduces characters of Near Field Optical Disc (NFOD) Recording Technique. The paper presents electrical and optical waveguide process problems in corn-shaped optical head of NFOD. It also put forward to the three grades approximate model of ultra-small-size laser firstly and simulate calculations in first-grade approximation of corn-shaped optical head of NFOD. The result give the relation between laser's input current and output power and the near field output light intensity pattern, and it is an important basis for the NFOD optical head design with ultra thin active layer and ultra small spot laser.
