PROBLEM TO BE SOLVED: To satisfactorily perform magnetic recording in a recording area in a main magnetic film with respect to a magnetic recording medium in which a magnetic pattern is formed by ion doping, and to provide a method for manufacturing the same, and a magnetic recording and reproducing apparatus. SOLUTION: The magnetic recording medium includes: a substrate 2; and a recording film 3 formed on the substrate 2 and including the main magnetic film 6 where a recording area 9 and a guard area 10 having saturation magnetization smaller than that of the recording area 9 are formed by local ion doping. A primary layer 5 is provided at the glass substrate 2 side of the main magnetic film 6. A main ingredient of the primary layer 5 is at least one element selected from among Cr, B, Mo, Al, Si, and C.
