| 摘要 |
The present invention aims to provide a magnetic recording medium improved in recording density, with maintaining various performances thereof, an efficient process for manufacturing the magnetic recording medium, and a nanoparticle for a magnetic recording medium sufficiently utilized therefor. The nanoparticle for a magnetic recording medium of the present invention has an organic compound capable of generating carbon adhering to the surface thereof, or 7 nm or less of a number average particle diameter thereof, or 0.1 or less of a particle distribution (distribution width (sigma)/particle diameter (D)) thereof. The magnetic recording medium of the present invention has a recording layer containing the nanoparticle for a magnetic recording medium. The process for manufacturing a magnetic recording medium of the present invention includes a step of applying, onto a substrate and in a magnetic field, a nanoparticle dispersed liquid in which the nanoparticle for a magnetic recording medium is dispersed.
