Abstract
A near held 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 mum x 0.2 mum 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 s tudy demonstrates the capability to achieve a very high areal density beyon d 20 Gb/in(2).
