摘要： A position sensor comprises a magnetoresistive element (1). The magnetoresistive element (1) comprises a stack (11) of layers including at least a conductive layer (112) in between two magnetic layers (111,113). The layers have a longitudinal extension (L) along a longitudinal axis (X) and a lateral extension along a transverse axis (Y). A magnet (2) is provided comprising a magnetic dipole (N/S) with a dipole axis (DA) orthogonal to a plane defined by the longitudinal axis (X) and the transverse axis (Y). The electrical resistance of the conductive layer (112) depends on a position of the magnet (2) along the longitudinal axis (X). The position sensor provides for nano-scale sensing.

摘要： A sensor arrangement for position sensing comprises a first magnetoresistive element (1) and a second magnetoresistive element (2). A magnetic field source (3) provides a magnetic field with a first magnetic pole (N) and a second magnetic pole (S). The magnetic field source (3) is arranged between the first magnetoresistive element (1) and the second magnetoresistive element (2) with the first magnetic pole (N) facing the first magnetoresistive element (1) and the second magnetic pole (S) facing the second magnetoresistive element (2). The first magnetoresistive element (1) is arranged in the magnetic field and provides a first output signal (R1) dependent on a position of the first magnetoresistive element (1) relative to the magnetic field source (3). The second magnetoresistive element (2) is arranged in the magnetic field and provides a second output signal (R2) dependent on a position of the second magnetoresistive element (2) relative to the magnetic field source (3). A measurement unit is configured to determine a position of the magnetic field source (3) relative to the first and the second magnetoresistive elements (1, 2) dependent on the first output signal (R1) and the second output signal (R2).

摘要： Method for operating a storage device with a tape (TP) and a head (HU) wherein the head (HU) comprises a first and a second read element (RE1, RE2). Each read element (RE1, RE2) is operable to detect servo-pattern of a particular servo band (SP). The first and the second read element (RE1, RE2) are arranged in such a way, that the tape (TP) at first passes one of both read elements (RE1, RE2) and subsequently passes the other of both read elements (RE1, RE2) when the tape (TP) moves in a predetermined longitudinal direction (X). A tape transport direction (TPDIR) of the tape (TP) along the longitudinal direction (X) is determined. The first read element (RE1) is selected dependent on the determined tape transport direction (TPDIR), when the determined tape transport direction (TPDIR) represents a direction where the tape (TP) at first passes the first read element (RE1) and subsequently the second read element (RE2). Otherwise the second read element (RE2) is selected. A position error signal (PES1) is determined dependent on the selected read element. With respect to a predetermined lateral reference point (REF) an estimated lateral track position ( d est ) at a longitudinal position (x1) of the selected read element is estimated dependent on the determined position error signal (PES1). With respect to the predetermined reference point (REF) another estimated lateral track position ( d* est ) at a longitudinal position (x2) of the non- selected read element is estimated in such a way that the other estimated lateral track position ( d* est ) becomes a time-delayed representation of the estimated lateral track position ( d est ).

摘要： 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.
