According to embodiments of the present invention, a probe storage medium includes a conductive layer as an electrode and a metal, metalloid, and/or non-metal doped diamond-like carbon (DLC) layer disposed on the conductive layer. A probe array may be positioned close proximity with the layer of doped DLC. An individual probe in the probe array may have an atomic force microscope tip. The probe storage medium may be written to by applying a current, voltage, and/or power to the tip between a thresholds current, voltage, and/or power value and a limiting current, voltage, and/or power value. The current, voltage, and/or power cause the layer of DLC to change conductance. The probe storage medium may be read by applying a current, voltage, and/or power to the tip below a threshold current, voltage, and/or power value and sensing the conductance.
