Magnetic recording medium, method for producing ε-type iron oxide-based compound particles, and method for producing magnetic recording medium |
| abstract |
The present invention provides a magnetic recording medium containing ε-type iron oxide-based compound particles as a magnetic material and suppressing the decrease in SNR after repeated sliding, a method for producing ε-type iron oxide-based compound particles, and a magnetic recording medium. Manufacturing method. The magnetic recording medium has: a non-magnetic support; and a magnetic layer, which is provided on at least one surface of the non-magnetic support and contains particles of an ε-type iron oxide compound and a binder, and is measured on the surface of the magnetic layer The contact angle of 1-bromonaphthalene is in the range of 30.0° or more and less than 45.0° for 1-bromonaphthalene, and in the range of 80.0° or more and 95.0° or less for water. |
