Scratches in a soft polymer cover-layer on near-field recording (NFR) media are observed after a servo test with a rotating disc owing to collision between a solid immersion lens (SIL) and a NFR disk. A dielectric protective film is coated on the cov

First, it is concluded that re-designing the objective lens of system is a good method to obtain maximum performance at fixed refractive index of media. Also, two systems cutting SIL and none cutting SIL were compared as re-designing objective lens.

In the near field recording (NFR) system, tilt margin between disc and solid immersion lens (SIL) is affected by the geometric features of the SIL. If the tilt angle is larger than the allowable tolerance, SIL can touch the surface of a disc and stab

Gap servo systems based on one of near field technologies are generally using the 1-beam push pull method to generate servo signal and this causes the optical DC offset problem in servo signal. In this paper, we presented new method of track error ge
