<p>PURPOSE:To eliminate a magnetic flux to enter deeply the magnetic body layer, to remove the thickness loss of the magnetic body layer and to attain a high density recording, by using a superconductive substance having a minus effect on a leaf spring. CONSTITUTION:On a leaf spring 13 and on this, a superconductive press fitting body 18 is formed and a press fitting pad is constituted. The press fitting body 18 is formed by a superconductive substance having a minus effect. As such a result, a magnetic flux to occur from a magnetic head 17 cannot enter deeply a magnetic body layer 16 by the minus effect of a piezoelectric body 18.</p> |
