Abstract
Various illustrative aspects are directed to a data storage device, comprising one or more disks; an actuator mechanism configured to position one or more heads proximate to a corresponding disk surface of the one or more disks; and one or more processing devices. The one or more processing devices comprise read/write circuitry which comprises an asynchronous demodulation module. The asynchronous demodulation module is configured to receive demodulated null burst signals based on the selected head reading servo burst fields of the corresponding disk surface; and output, based on the demodulated null burst signals, a radial position signal, indicative of a radial position of the selected head.
