摘要： Timing based servo bursts of servo frames, in which the frames are arranged to be symmetric with the same number of servo stripes in each burst of a frame, are synchronized by shifting selected bits. For example, servo frames are arranged with four servo bursts with an equal number of servo stripes in each burst, the servo frames comprising two symmetric sub-frames, each sub-frame comprising two bursts of servo stripes that are parallel to each other within a burst, and the bursts are non-parallel with respect to each other; each servo burst is arranged to comprise at least one reference servo stripe; and each servo burst is arranged to comprise at least one shifted servo stripe, wherein the shift is in the same longitudinal direction with respect to at least one reference servo stripe for each burst of a frame and the opposite longitudinal direction for bursts of sequentially adjacent frames.

摘要： Servo control methods and apparatus for a tape drive. A read/write head reads and writes data on magnetic tape with at least one servo track providing transverse position information. At least two servo readers arranged for reading a servo track associated with the read/write head operate concurrently to generate servo read signals. A position estimator processes each servo read signal to generate a series of position values corresponding to respective time instants indicative of their transverse positions. A servo controller calculates a skew value indicative of tape skew relative to the read/write head and a tension variation value indicative of variation of tape tension. The servo controller is adapted to account for cross-coupling between tape skew and tension variation.

摘要： A method and a scanning probe microscope (SPM) for scanning a surface of a material. The method and SPM have a cantilever sensor configured to exhibit both a first spring behavior and a second, stiffer spring behavior. While operating the SPM in contact mode, the sensor is scanned on the material surface and a first spring behavior of the sensor (e.g. a fundamental mode of flexure thereof) is excited by deflection of the sensor by the material surface. Also while operating the SPM in contact mode, excitation means are used to excite a second spring behavior of the sensor at a resonance frequency thereof (e.g. one or more higher-order resonant modes) of the cantilever sensor to modulate an interaction of the sensor and the material surface and thereby reduce the wearing of the material surface.

摘要： The present invention relates to a method of reducing the wear of a tip of a probe when the tip is in contact with a surface of a substrate and when the probe is mounted on a support structure. A method is provided where a load force is applied to the probe, thereby causing the tip to be maintained substantially in contact with the substrate surface and a modulation step where the e magnitude of the load force is modulated at a modulation frequency. The modulation frequency is selected to be greater than a fundamental vibration frequency of the support structure on which the probe is mounted.

摘要： A device for guiding a magnetic tape in a data storage drive including a cylindrical body rotatable about a longitudinal axis. The cylindrical body having opposing ends and defining a surface area for mating with a magnetic tape. A curved section at opposite ends of the cylindrical body is contiguous with the surface area of the cylindrical body. A plurality of vents in the cylindrical body allow air flow therethrough between the surface area and the tape. The amount of air flow between the cylindrical body and the tape produces varying frictional forces on the tape such that the tape is biased to a nominal position on the cylindrical body by air pressure on the tape resulting from the air flow interaction with the curved sections.

摘要： There is disclosed a tape guide roller for guiding a tape (11) in a tape storage. The tape guide roller is tiltable such that by tilting the tape guide roller the tape (11) may be returned from a laterally offset position to a centered position. An actuator (1560) of the tiltable tape guide roller is implemented as a magnetic actuator with a permanent magnet assembly (1570) and an electromagnet a pole piece (1702) of which electromagnet is facing the magnet assembly (1570). The width (W1) of the pole piece (1702) is smaller than the width (W2) of the magnet assembly (1570). As a result the tape guide roller may be operated in a power efficient way.
