PROBLEM TO BE SOLVED: To obtain a method for forming a servo tracking pattern on a magnetic disk by magnetic transfer even if a recording density is improved.;SOLUTION: The eight types of burst signal patterns, which are displaced by 1/8 pitches for each in a radial direction, have been formed on a master disk using a magnetic material and a nonmagnetic material, and then the master disk is superimposed with a medium 7, and a DC exciting magnetic field is applied by a head 20 in a direction of 45 degrees to a track, thereby burst signal patterns having components in both of a radial direction and a track direction are magnetically transferred to a reproduction signal of the medium, and positioning of a read head is performed based on the burst signals, thereby size of a servo tracking pattern is reduced, and positioning control of the head is achieved even if the size of the read head is reduced to not more than 0.1 m.;COPYRIGHT: (C)2005,JPO&NCIPI
