PROBLEM TO BE SOLVED: To provide a magnetic transfer method capable of performing good magnetic transfer for a perpendicular magnetic recording medium, the perpendicular magnetic recording medium based on the magnetic transfer method, and a magnetic recording device incorporating the perpendicular magnetic recording medium. SOLUTION: The magnetic transfer method includes the magnetic transfer step of transferring the magnetic pattern of a master disk to a slave disk by applying the transfer magnetic field of a parallel direction to a substrate surface while bonding the master disk 46 as a disk substrate having a pattern constituted of the array of magnetic layers according to information to be transferred to the slave disk 40 as a perpendicular magnetic recording medium formed in its surface, and the servo correction information writing step of writing servo correction signal information in a place adjacent to the information transferred to the slave disk by the magnetic transfer step by a magnetic head.
