Magnetic recording method and magnetic head

DETAILED DESCRIPTION In accordance with the present invention, a magnetic recording method is provided in which desired information is recorded on a main track of a magnetic disk using a magnetic head.
Subsequently, other information is recorded on a guard band adjacent to the recorded main track using a magnetic head having a predetermined azimuth angle.
The magnetic head for recording the main track is applied with a so-called optimum recording current.
The magnetic head for recording the guard band is applied with a recording current so that its magnetomotive force is within the range of 40% to 80% of the magnetomotive force of the magnetic head for recording the main track.
A magnetic head according to the present invention is a composite thin film magnetic head comprising integrally a first magnetic head for recording and reproducing first information on the main track of the magnetic disk and a second magnetic head for recording and reproducing second information on the guard band adjacent to the main track.
Each of the first and second magnetic heads is a thin film magnetic head comprising a magnetic layer, an insulator layer, and a conductor layer formed of thin films.
The magnetic heads are disposed adjacent to each other in the widthwise direction of the track with a certain azimuth.
Another magnetic head is also provided according to the present invention which comprises a plurality of head chips disposed on the same plane of a head base plate with different azimuth angles, in which the plane of the head base plate having the head chips is slanted relative to the longitudinal direction of the track so that a plurality of tracks are formed on the magnetic disk by the individual head chips with no gaps.
