Abstract:
A magnetic recording medium includes a tape-shaped nonmagnetic support, and a vertical magnetic layer formed on a main surface of the nonmagnetic support by a vacuum thin-film forming technique, signals being recorded on and reproduced from the vertical magnetic layer in a linear system. In the magnetic recording medium, the dipulse ratio of the vertical recording layer is 0.36 or more.
