| abstract | [57] [Problem] To provide a magnetic recording medium having excellent magnetic durability by adding a specific substance that satisfies light transmittance, thereby reducing the thickness of a magnetic coating film, reducing the amount of carbon added, improving electromagnetic conversion characteristics, and improving durability. The purpose is to obtain. The present invention relates to a magnetic recording medium provided with a magnetic layer on one surface of a non-magnetic support. This magnetic layer contains a ferromagnetic powder, a near-infrared region absorbent, and carbon black. Here, as the near infrared region absorbent, 3,3′-diethyl-9,11,1 5,17-dineopentylene-thiapentacarbocyanine perchlorate was used. The content of the near infrared region absorbent is 0.25 to 1.0 with respect to 100 parts of the ferromagnetic powder. Part is desirable. The content of carbon black is desirably 0 to 5 parts with respect to 100 parts of the ferromagnetic powder. As a result, the thickness of the magnetic recording medium for the VHS system can be reduced. Also, the addition of the near-infrared region absorber alone can satisfy the demand for the reduction in light transmittance. |
