Abstract
A magnetic recording and reproducing apparatus includes a magnetic head having a main magnetic pole, a magnetic recording medium of a discrete type having a predetermined convex-concave structure at data tracks and servo tracks, and a drive device body that can operate to rotationally drive the magnetic recording medium in a constant direction and cause the magnetic head to be movable in substantially radial directions of the magnetic recording medium. A relationship among parameters specifying a predetermined convex-concave shape of the data track, parameters specifying the main magnetic pole, and a skew angle is defined by a predetermined inequality. By setting a specification of the magnetic recording and reproducing apparatus in the range defined by the inequality, it is possible to prevent unwanted writing into the adjacent track to thereby realize high-density recording having extremely high reliability.
