A master pattern having a plurality of tracks is recorded on the disc. Each track on the disc includes a plurality of magnetic islands, each having a size and magnetic properties. The size and/or magnetic properties of one or more of the magnetic islands of each track are modulated such that each track has a modulation frequency, so as to imprint a magnetic topology on the disc. The modulation frequency of each track is either a fundamental frequency or an overtone of the fundamental frequency.

摘要： The active vibration suppression of a slider suspension arm is achieved by including as part of the suspension arm two bimorph piezoelectric elements. A first bimorph piezoelectric element is attached to the top of the suspension arm and acts as a sensor. A second bimorph piezoelectric element is attached to the bottom of the suspension arm and acts as an actuator. The actuator is controlled as a function of a voltage measured by the sensor so that the actuator damps periodic vibrations occurring in the suspension arm.
