Estimating the term…
The present invention provides data storage devices, systems and methods. An example device includes: a storage medium for storing data in the form of marks; and at least one probe. The probe(s) and storage medium are 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. The force creating units are operable to create a force acting between the tip and said storage medium. The data storage device is operable to erase an indentation mark in the storage medium by way of controlling the 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.
A data storage device comprising:
A data storage device according to claim, wherein said erase force pulse comprises a rise in said force during said erase force pulse in the range from 10 nN up to two orders above.
A method for controlling a data storage device comprising a storage medium for storing data in the form of indentation marks;
Dependencies are inferred from the claim text.
