Magnetic recording medium, its production method and magnetic recording apparatus

摘要

A magnetic recording medium for recording information by forming a magnetic pattern for information thereon by a magnetic head, which is a longitudinal magnetic recording medium having a coercive force of at least 3000 Oe, and which has a magnetic pattern for control of the magnetic head preliminarily formed thereon, wherein the full width at half maximum of an isolated pulse of a reproducing signal of the magnetic pattern for control is smaller than the full width at half maximum of an isolated pulse of a reproducing signal of the magnetic pattern for information.
