Summary:PROBLEM TO BE SOLVED: To provide a technique of providing a perpendicular magnetic recording medium in which high-quality servo information enabling high-density recording of 500 kTPI or more is recorded, and a magnetic storage device of an adaptive track formatting type having large capacity, high reliability and high performance with high device manufacturing yield.SOLUTION: At a servo area of the perpendicular magnetic recording medium, a servo sequence such as a burst pattern for positioning in a servo track is recorded in a seamless manner without recording footprint and in a magnetization pattern such that a total amount of the recording magnetization is substantially zero.
