Title: Magnetic recording medium
Inventor: HARA SHINICHI
IPC: C09D5/23
Filed: 1983-12-19
Abstract: PURPOSE:To improve the repetitive driving properties with reduction of the friction coefficient and to eliminate the squeak for a magnetic tape, by dispersing the fine powder of glass type carbon into a magnetic layer. CONSTITUTION:The glass type carbon has a small friction coefficient and excelllent wear resistance. Thus a magnetic recording medium containing a magnetic layer mixed with the fine powder of the glass carbon also has a small friction coefficient and excellent wear resistance. In this case, the friction coefficient is reduced as the amount of the glass carbon fine powder is increased with more excellent wear resistance for the magnetic recording medium. However, the magnetic characteristics are deteriorated as the amount of said fine powder is increased. While no satisfactory effect is obtained if the amount of the fine powder is less than the prescribed value. Therefore the amount of the carbon fine powder is preferably set at 1-50wt% to the total amount of magnetic coating material and especially at 5-20wt%.
