Abstract

PURPOSE: To obtain an erasing head which can erase completely data on a high- density recording and high-coercive-force tape by using magnetic alloy with one of chrominium, tungsten, tantalum and titanium, etc., added to a specific amount of nickeliron as a core material.
CONSTITUTION: An erasing head is formed of the material that can improve permeability and electric resistance as a core material which one of chrominium, tungsten, tantalum, germanium, cabalt and titanium, etc., of 20% in total amount is added to nickel-iron alloy of 35W70% in weight ratio. As a result, magnetic and electric characteristics can erase data on a magntic tape sufficiently which has been recorded in high density.
