Abstract

PURPOSE:To obtain a magnetic head having high density recording and high S/N by providing a superconduction shield formed with a recording gap at the outside of a superconduction coil. CONSTITUTION:The superconduction shield case 4 is provided on the outside of the superconduction coil 2 and the recording gap 3 and the leakage gap 1 of the coil 2 are overlapped and a gap spacer 6 is provided in the overlapped gaps 1, 3. A magnetic field generated in a cavity 5 in the coil 2 is repulsed by the Meisner effect of the superconduction coil 2 and passes through the cavity 5 without being almost leaked externally and leaked externally from the gap 1 of the coil 2 and the recording gap 3 of the superconduction shield case 4 to form leaked magnetic flux. Thus, high magnetic flux density is obtained and magnetic recording capability is improved. Moreover, the leaked magnetic flux from the superconduction coil 2 to the magnetic medium is shut up completely to improve the S/N.
