    Abstract: PCT No. PCT/EP93/03079 Sec. 371 Date May 2, 1996 Sec. 102(e) Date May 2, 1996 PCT Filed Nov. 3, 1993 PCT Pub. No. WO95/12882 PCT Pub. Date May 11, 1995An apparatus and a method for retrieving data stored on a magnetic medium with a high resolution is described. It is characterized by measuring a tunneling current which is partly depending on the magnetization of the medium (1). This dependence is caused by irradiating the medium (1) with polarized non-ionizing light. The tunneling current can be measured with a high lateral resolution by applying a probing tip (2) as known from conventional scanning tunneling microscopy or related techniques.
