Abstract

PURPOSE:To obtain a magnetic head which does not receive the effect of temperature change by using two sets of cores in whose temperature characteristics of magnetic permeability offset. CONSTITUTION:If the head is formed by combining cores 3, 4 of magnetic permeability whose temperature characteristics mutually offset, the magnetic permeability owing to temperature change becomes smaller and the characteristics such as impedance, etc. are not affected by temperature change, thus the good head may be obtained.
