Abstract

PURPOSE:To make the production of an abration resistant magnetic head having a charging characteristic preventing function easy and sure by directly bonding non- magnetic material of the specified low resistivity, coefficient of thermal expansion and hardness to ferrite cores. CONSTITUTION:If the magnetic ceramic members constituting sliders 3 are constituted by black barium titanate obtained through reduction sintering in a CO gas atmosphere or non-magnetic ferrite of many Zn components at ordinary temperature, then they are non-magnetic and their coefficient of thermal expansion and hardness become approximately the same as those of a read-write ferrite core 1 and erase cores 2, 2. In addition, their resistivity becomes as low as 10<8>OMEGAcm or under. Since these sliders 3, 3 and cores 2, 2 are approximately equal in the coefficient of thermal expansion, they may be readily and surely bonded and the generation of static electricity which impairs the performance is provented owing to the low resistance of the sliders 3, 3. Hence, the small magnetic head which has a antistatic function and is large in abrasion resistance may be readily made.
