摘要： In a magnetic recording system including magnetic recording media, a rotation driving unit for driving these magnetic recording media, read/write magnetic heads, driving apparatus for driving these read/write magnetic heads, and a read/write signal processing apparatus, a reading portion of the respective magnetic heads is arranged by a magnetoresistive head. The magnetic recording media are constructed of multi-layered magnetic media having a plurality of magnetic layers fabricated directly, or via underlayers on a non-magnetic disk substrate, and of non-magnetic intermediate layers arranged among these non-magnetic layers. Furthermore, one coercivity which is measured by applying a magnetic field along a circumferential direction of the magnetic recording media, is selected to be larger than the other coercivity which is measured by applying a magnetic field along a radial direction of the magnetic recording media, so that a higher signal-to-noise ratio is achieved, as compared with that of the conventional magnetic recording system. Since the thickness of the non-magnetic intermediate layers is smaller than or equal to 5 nm, and also the total layer is smaller than or equal to 5 nm, and also the total layer number of the plural magnetic layers is selected to be odd, better characteristics can be achieved. Accordingly, since the MTBF (Mean Time Before Failure) is longer than or equal to 0.15 million hours with high recording density, and the disk substrate and the magnetic head sliders can be mounted at high packaging density, a compact and high-capacity magnetic recording system can be obtained.

摘要： A magnetic recording system includes an intermediate layer arranged between adjacent ones of a plurality of magnetic layers constituting a magnetic recording medium, the magnetic recording medium driven by a drive section in the recording direction, and a magnetic head including a write section and a read-back section set in relative motion with respect to the magnetic recording medium. Signals are applied to the magnetic head and the output signals from the magnetic head are read back by a read/write signal processing device. The read-back section of the magnetic head includes a magnetoresistive magnetic head. The magnetic layers of the magnetic recording medium include crystal grains having different crystal orientations and existing in overlapped positions in the direction perpendicular to the medium surface. High-density information read/write operation thus is made possible with an improved reliability.
