A method of scanning over a substrate includes implementing a write mode of the substrate by scanning a probe across a substrate, the probe having a spring cantilever probe mechanically fixed to a probe holding structure, a tip with a nanoscale apex, and an actuator for lateral positioning of the tip; the actuator comprising a thermally switchable element and a heating element for heating the thermally switchable element; and heating the heating element to a given temperature so as to locally soften a portion of the substrate and applying a force to the softened portion of the substrate through the tip so as to create one or more indentation marks in the softened portion of the substrate.

A cantilever device for scanning a surface comprises a support, a tip platform and a flexible arm arrangement. The tip platform has a plurality of tips. These comprise at least two contact tips providing points of contact with a surface to be scanned, and a scanning tip for scanning the surface, where the scanning tip may be one of the two or more contact tips provided on the platform. The flexible arm arrangement connects the tip platform to the support and allows orientation of the platform, via flexing of the arm arrangement, to bring the contact tips into contact with a surface to be scanned. The platform is then at a well-defined orientation relative to the scan surface, and the scanning tip is appropriately positioned for the scanning operation. Scanning probe microscopes and data storage devices incorporating such cantilever devices are also provided.

A data storage device comprises a storage medium for storing data in the form of marks and at least one probe for scanning the storage medium. The storage medium may be comprised in a substrate. The probe comprises a cantilever that comprises terminals serving as electrical contacts an being during operation of the probe mechanically fixed to a probe-holding structure, which may be a common frame of the data storage device. A probe further comprises a supporting structure, to which the terminals are mechanically directly coupled or coupled via hinges and which extends away from the terminals. A tip with a nanoscale apex is provided. A beam structure comprises a heating resistor and is attached at ends to the supporting structure. The beam structure is thinned at least in a direction parallel to an axis of the tip compared to an area of the supporting structure abutting the beam structure.
