Amplitude servo pattern, magnetic recording medium and the manufacturing method, patterned magnetic transfer master substrate used in the manufacturing method, and magnetic recording/reproducing apparatus

摘要

An amplitude servo pattern capable of providing accurate servo control through reproduced amplitude with reduced noise is provided. The amplitude servo pattern has servo burst signals composed of burst bit strings adjacently disposed in a track width direction. The burst bit strings are disposed such that the servo burst signals adjacently disposed in the track width direction have a phase difference with each other in a track direction.
