Abstract: PROBLEM TO BE SOLVED: To obtain reproduced signal quality in which the SN ratio is high and crosstalk is small by approaching close to and performing relative movement to a magnetic recording medium and setting, along the moving direction, a magnetic flux detection area where the magnetic domain pattern of a reproduction having a length equal to or greater than the shortest record wavelength of the magnetic domains of a pair of memory layers adjacent to each other and directed oppositely to the magnetic recording medium. SOLUTION: A record magnetic domain surrounded by a pair of the arcs of a magnetic domain wall moving type recording media consists of upward magnetic domains denoted by a white circle symbol with a black point inside and downward magnetic domains denoted by a white circle symbol with a cross mark inside. A curve group 9 is an isotherm group and as an isotherm is located close to the left, it represents a higher temperature. A magnetic field detection area 8 is an area where a magnetic head can detect a magnetic field with high sensitivity, and the length of the area 8 is almost equal to the thickness Lt of a main magnetic pole. Here, the thickness Lt of the main magnetic pole is made wider than the shortest record wavelength λ occupied by a pair of record magnetic domains adjacent to each other and directed oppositely.  Thus, it is possible to perform low noise magnetic domain wall moving type reproduction and to prevent the reduction of the SN ratio of a reproduced signal.
