Abstract

PURPOSE: To perform ultra-fine recording by providing superconducting films respectively provided with minute openings between a magnetic line of force generating means and recording medium as slits and performing the recording by magnetizing the recording medium by the magnetic line of force passing through the slits of the magnetic line of force produced by the magnetic line of force generating means.
CONSTITUTION: Superconducting film slits 13 and 14 are provided perpendicular to the magnetic field 12 produced when a signal current flows through a coil 11. The slits 13 and 14 are respectively provided with pin holes 15 and 16 and are arranged in such a way that part of the magnetic flux 17 of the magnetic field 12 by means of the coil 11 can pass through the pin holes 15 and 16. A tape-like recording medium 18 is placed perpendicular to the magnetic flux 17 in the vicinity of the superconducting film 14. The magnetic flux 17 passing through the pin holes 15 and 16 is projected on the recording medium 18 as a pin hole having a diameter which is almost the same as that of the pin holes and magnetizes the vertical particles of a magnetic substance in a prescribed direction. Therefore, recording of a fine particle level becomes possible and the recording density can be improved.
