Title: Magnetic recording medium
Inventor: WAKANA SHIGEAKI
IPC: G11B5/73
Filed: 1992-07-30
Abstract: PURPOSE:To obtain a magnetic recording medium which is excellent in recording and reproducing characteristics and durability by constituting the medium so that the Rsk value indicating the degree of profile asymmetry of the medium with respect to its center line can become negative. CONSTITUTION:The recording medium is constituted by forming a magnetic layer on a nonmagnetic substrate so that the Rsk expressed by equation 1 can become a negative value. In the expression, Yi, Rq, and (n) respectively represent the distance from the center line to a crest or trough (positive on the crest side and negative on the trough side) of the medium, root-mean-square value of the surface roughness of the medium, and the number of Yi data. In most cases, the crest side is relatively flat when the Rsk is negative. Therefore, when a lubricant layer is provided on the surface of the medium, it is presumed that the lubricant layer exists even at the front end section on the crest side. As a result, it is inferred that the sliding characteristic of the medium against a magnetic head is excellent and, actually, the sliding characteristic and recording and reproducing characteristics of the medium are excellent.
