Abstract: A magnetic recording medium is a magnetic recording medium having a tape shape and includes a substrate, an underlayer provided on the substrate, and a magnetic layer provided on the underlayer. The magnetic layer has a surface having an uneven shape, a height range ?H obtained from statistical information of a height of the uneven shape is in a range of 4.00 nm??H?10.00 nm, and a gradient range ?A obtained from statistical information of a gradient of the uneven shape is in a range of 2.50 degrees ??A.

Abstract: An object is to suppress or prevent a dimensional change of a magnetic recording tape. The present technology provides a magnetic recording tape having a layer structure including a magnetic layer, a base layer, and a back layer in this order, in which a reinforcing layer containing a metal or a metal oxide is disposed on either a surface of the base layer on the magnetic layer side or a surface of the base layer on the back layer side, and a black area in an image obtained by binarizing an optical microscope image of a rectangular region of 64 ?m×48 ?m of the reinforcing layer is 300 ?m2 or less.

Abstract: A magnetic recording medium includes: a substrate that is long in shape; and a magnetic layer containing magnetic powder and a binder. The glass transition point of the binder is not lower than 75° C. In a case where atomic force microscope observation images in a 10 ?m×10 ?m rectangular shape are acquired at five locations randomly selected from the surface on the side of the magnetic layer, any linear protrusion that is 3 nm to 20 nm in height, is 0.3 ?m to 1.0 ?m in width, and extends across two sides of the observation image does not exist in the observation images of four locations among the acquired observation images of the five locations.
