    Abstract: A method and apparatus for overwriting data in a probe-based data storage device wherein data is represented by the presence and absence of pits formed in a storage surface by a probe of the device is provided. Input data is first coded such that successive bits of a given value x in the coded input data (b0, b1, b2, . . . ,) are separated by at least d bits of the complementary value {tilde over (x)}, where d is a predetermined number>=2. Overwrite data bits (v0, v1, v2, . . . ,) are then generated by encoding the coded input data bits (b0, b1, b2, . . . ,).

    Abstract: A storage device and a method for scanning a storage medium. A storage medium for storing data in the form of marks is scanned by an array of probes for mark detecting purposes in a scanning mode. The storage medium has fields with each field to be scanned by an associated one of the probes. At least one of the fields has marks representing operational data for operating the scanning mode. Scanning parameters are computed from the operational data and the scanning mode is adjusted according to the computed parameters.

    Abstract: A data storage device comprises a storage medium, at least one probe designed for creating indentation marks in the storage medium, a control unit designed for creating a control parameter (CTRL) acting on the probe resulting in the creation of one indentation mark. The control unit is further designed for modifying the control parameter (CTRL), if at least a given number of consecutive indentation marks with a given minimum distance between each other should be created. According to the method the control parameter (CTRL) is modified if at least a given number of consecutive marks with a given minimum distance between each other should be created.
