Magnetic recording system providing a magnetic head having opposite sides for applying different magnetic field strengths to a magnetic recording medium

A magnetic recording device for recording information on a magnetic recording medium for forming a perpendicular magnetization component using a ring head, said ring head being constituted by cores and a coil wound therearound, one of the cores having a leading side and the other core having a trailing side, said leading side and said trailing side being disposed to oppose each other across a prescribed gap, said device comprising:

• a ring head being structured such that the magnetic field strength to be generated on said leading side is have a difference from a magnetic field strength to be generated on said trailing side;
• and
• means for determining said difference of said magnetic field strength such that a waveform reproduced by said reproducing head from a magnetization to be recorded by said device on the magnetic recording medium is a single-peak wave form,
• wherein the magnetic field strength on the leading side greater than the magnetic field strength on the trailing side so that a single-peak waveform is formed on the magnetic recording medium, a portion having a saturation magnetic flux density greater than that on the trailing side is disposed on said leading side and a portion having a saturation magnetic flux density smaller than that on said trailing side is disposed on said trailing side.

• a ring head being structured such that the magnetic field strength to be generated on said leading side is caused to have a difference from a magnetic field strength to be generated on said trailing side;
• discriminating means for discriminating a recording-type specification of the magnetic recording medium, and means for causing said trailing side to run earlier in time than said leading side in relative movement with respect to the magnetic recording medium depending on an output produced by said discriminating means;
• and
• means for adjusting a recording current such that a waveform to be recorded by said device on the magnetic recording medium is a single-peak waveform.
