Magnetic recording medium and magnetic recording and reproducing system

A magnetic recording and reproducing system comprising a magnetic recording medium, and a magnetic head for writing or reading information relative to said magnetic recording medium,

• wherein said magnetic recording medium is a disc-shaped magnetic recording medium on which magnetic tracks for writing and reading magnetic information are arranged substantially concentrically,
• wherein, a saturation magnetic field in a width direction extending in a radial direction from the center of the disc-shaped magnetic recording medium is HR, and a saturation magnetic field in a circumferential direction perpendicular to said radial direction is HC, HR/HC is set to a value within a range of 0.5 to 0.95 in each of said magnetic tracks, and magnetization information is recorded in the width direction of each magnetic track,
• wherein, in gap portions between the magnetic tracks located adjacent to each other in said radial direction, discrete portions for magnetically separating the adjacent magnetic tracks are formed, respectively,
• wherein said magnetic head comprises a recording head portion having a recording gap for recording the magnetization information in the width direction of the magnetic track, and a reproducing head portion having a reproducing gap for taking in the magnetization information recorded in the width direction of the magnetic track,
• wherein a relationship between a length (G1) of the recording gap of said magnetic head and a track width (TW) of said magnetic recording medium satisfies 1.5≧(G1/TW)≧0.9, and
• wherein a relationship between a length (G2) of the reproducing gap of said magnetic head and the track width (TW) of said magnetic recording medium satisfies 1.2≧(G2/TW)≧0.75.
