Abstract

A magnetic recording method for recording a digital signal in the form of a two dimensional plane on a magnetic recording medium like a magnetic tape, a magnetic disc etc. Magnetic flux is generated according to a shape of the surface of the magnetic recording head facing the recording medium. Thus, digital information is recorded on the recording medium in the form of two dimensional information according to the shape of the surface of the magnetic head. A magnetic recording medium on which two dimensional information has been recorded by the above recording method, and a reproducing method for reproducing the recorded information on said magnetic recording medium are also disclosed.
