<P>PROBLEM TO BE SOLVED: To make it possible to perform satisfactory magnetic recording to recording areas in a main magnetic film in a magnetic recording medium in which a magnetic pattern is formed by ion implantation, its manufacturing method and a magnetic recording and reproducing apparatus. Ž<P>SOLUTION: A manufacturing method of a magnetic recording medium having a plurality of magnetic recording areas 9A and isolation areas 10 magnetically isolating the magnetic areas 9A in a hard magnetic layer 6 formed on a glass substrate 2 includes a step of forming the hard magnetic layer 6 made of a hard magnetic material having a magnetic coercive force whereby magnetic recording is impossible on the glass substrate 2 and a step of performing ion implantation partially at positions corresponding to the magnetic recording areas of the hard magnetic layer 6 so that the magnetic recording areas 9A are formed by reducing the magnetic coercive force in the positions of the ion implantation to a magnetic-recordable magnetic coercive force, and specifying areas except the recording area 9A forming areas to be the isolation areas 10 to maintain the magnetic coercive force whereby magnetic recording is impossible.
