Magnetic head comprised of an improved base substance for high density magnetic recording

A magnetic head is disclosed in which a non-magnetic base substance which supports a writing or reading converter for writing or reading on a magnetic recording medium is constructed with an aggregate of carbon material, or a composite material comprising an aggregate of carbon material, and a thermosetting resin and/or a carbonaceous filler.

Determination of Young's modulus and stress analysis of a magnetic coating medium

This paper proposes a method for determining Youngs modulus of a magnetic medium for which Youngs modulus of thin films composing it can not be measured directly. The particular internal stresses induced in bonded two thin films under tension are analysed by the finite element method (FEM). Among these stresses, the importance of shearing stress induced at the interface between two thin films is indicated.
