ملخص
A near field optical technique based on combined supersphere solid immersion lens (SIL) with magnetic field modulation (MFM) recording is described. A better resolution is achieved by using SIL with MFM recording in comparison with light intensity modulation (LIM). A recorded mark as small as 0.3 μm × 0.2 μm could successfully be detected. These marks were readout by the SIL head with a typical signal to noise ratio value of 36 dB. The present study demonstrates the capability to achieve a very high areal density beyond 20 Gb/in2.
