Magnetic recording material |
| abstract |
A magnetic recording material, which comprises a magnetic layer coated on a non-magnetic support is disclosed. The magnetic layer contains both carbon black fine powder having a mean primary grain size of less than 10 m mu and carbon black coarse powder having a mean primary grain size in the range of 50 to 120 m mu in a mixing ratio ranging from 95/5 to 5/95. The material is improved in both RF output and audio output. |
