Document Type and Number:
Japanese Patent JP4128135
Kind Code:
B2
Abstract:
A recording / reproducing head (100) is intended to perform at least one of a record operation of recording information onto a dielectric recording medium (20) and a reproduction operation of reproducing the information from the dielectric recording medium. The recording / reproducing head (100) is provided with: a support member (130) which extends in a longitudinal direction; a projection portion (110) which is mounted on the support member such that a tip of the projection portion faces the dielectric recording medium; and a conductive layer (120) which covers a part other than at least the tip out of the projection portion, the projection portion containing a harder material than that of the conductive layer.
