  • Magnetic head having boron carbide surfaces
    Patent number: 4885650
    Abstract: A magnetic head for reading or writing information magnetically encoded on a substrate is disclosed. Included in the head are a magnetic core and a boron carbide contact surface which the substrate rubs against during reading or writing. The boron carbide contact surface is electrically conductive and is resistent to wear. Grounding of the conductive boron carbide contact surface avoids static electric charge build up on the contact surface caused by rubbing of the substrate against the magnetic head.
