Title: Magnetic recording medium
Inventor: SHIMOZAWA TORU
IPC: G11B5/708
Filed: 1985-03-19
Abstract: PURPOSE:To eliminate the sticking due to triboelectricity and the cutting of a magnetic recording layer and to reduce dropouts by using graphitized carbon black. CONSTITUTION:The magnetic recording layer contains hexagonal plate barium ferrite magnetic powder and graphitized carbon black. A shell-like structure wherein carbon layer surfaces are arranged in parallel can be seen on the surface of the graphitized carbon black, voids are present in the vicinity of the center at the inside and a somewhat angular hollow capsule-shaped structure is also present. Consequently, graphitized carbon black is structurally different from carbon black and clearly discriminated by an electron microscope and the surface shell is smooth because the surface is graphitized. Since the friction is extremely low, the sliding due to triboelectricity is eliminated and water adsorption is low, traveling stability can be obtained when the medium is used under high temp. and humidity.
