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.
Claims24
Data storage device comprising
- a storage medium;
- at least one probe for creating one or more indentation marks in said storage medium;
- and
- a control unit for generating a control parameter for said at least one probe to create one of said one or more indentation marks;
- wherein said control unit modifies said control parameter when at least a given number (n_thr) of consecutive indentation marks are to be created at a given minimum distance between each other.
A method for operating a data storage device comprising a storage medium, at least one probe designed for creating indentation marks in said storage medium and a control unit, the method comprising the following steps performed by said control unit:
- creating a control parameter for said probe to create one of said indentation marks;
- monitoring the number of consecutive indentation marks to be created;
- and
- modifying said control parameter if at least a given number of consecutive indentation marks are to be created with a given minimum distance of each other.
