Device and method for mechanical data storage device operation and control

A data storage device comprising:

• a storage medium for storing data in the form of marks;
• and
• at least one probe, said at least one probe and said storage medium being operable to move relative to each other, with each probe comprising a tip facing the storage medium and having a force creating unit associated thereto, said force creating unit being operable to create a force acting between said tip and said storage medium, said data storage device being operable to erase an indentation mark in said storage medium by way of controlling said force creating unit for creating at least one erase force pulse with a force rise time being less than or equal to the order of 1 microsecond, wherein multiple erase force pulses are created for erasing one indentation mark and wherein a force pulse frequency of said multiple erase force pulses is at least 100 kHz.
