A method of operating a storage device includes storing data in the form of marks in a storage medium; scanning the storage medium with at least one probe operating in a scanning mode; and utilizing a control unit to provide a pulsed reading signal for data detecting in the scanning mode, and providing the probe with oversampling reading pulses in a clock mark scanning mode, wherein the control unit further comprises an input for a response signal to the oversampling reading pulses, and a determination unit for determining the clock dependent on the response signal; wherein the storage medium comprises marks for determining a clock of the pulsed reading signal. |
