摘要： A tape movement constraint for a tape drive system, comprises a tiltable tape roller bearing having a grooved surface adapted to contact and engage a surface of the tape as the roller barrel rotates, and an actuator adapted to pivot the roller bearing surface when the actuator is actuated, to control the lateral position of a tape. In operation, in one embodiment, a roller barrel of the tiltable roller bearing is biased in a first position on a pivot axis, using magnetic attraction between a movable magnet and a return path structure of magnetically permeable material. The roller barrel is pivoted on the pivot axis by conducting current through a fixed coil to generate a magnetic field which is conducted by the return path structure to interact with the magnetic field of the magnet. Other embodiments are described and claimed.

摘要： Described are embodiments to ensure that the equipment utilized to detect antigens is reliable and accurate. If it is determined that a read sensor is degraded a method of calibrating a read sensor of a read head is described. In one embodiment, a method of calibrating a magnetic read sensor includes measuring a first resistance of the magnetic read sensor upon an application of a forward bias current to the magnetic read sensor and measuring a second resistance of the magnetic read sensor upon an application of a reverse bias current to the magnetic read sensor. A calibration constant is determined based on at least the first measured resistance and the second measured resistance. In one embodiment the method further includes storing the determined calibration constant for the magnetic read sensor in memory. Further, in one embodiment the head module having the magnetic read sensor is swept over at least one nanoparticle to obtain a read response of the magnetic read sensor to the nanoparticle. The read response from the magnetic read sensor of the at least one nanoparticle is adjusted based on the determined calibration constant. Calibration of each individual read sensor allows for uniform read responses from each of the read sensors on a read head, and prevents unreliable an inaccurate detection of analytes due to sensor degradation.

摘要： A servo write head that provides fast servo pattern writing and improved tape manufacturing speed is provided. The write head may be fabricated using thin-film fabrication techniques. A coil is formed on a bottom pole of the write head. The coil has a plurality of turns that enable the write head to generate a magnetic field sufficient for writing data with reduced current. The inductance of the coil is reduced due to its small dimensions. Reduced inductance of the coil may enable increased switching frequency of the write head, allowing data to be written at a higher frequency. The write head includes a planar top pole coupled to the bottom pole. The top pole has more than one write gap is formed therein.

摘要： Magnetic nanoparticles are detected across a thin membrane that separates the nanoparticles from a magnetic sensor. The technique can be used in a medical context, in which an analyte of interest (present in a test fluid, such as blood) is attached to the membrane. Other compounds are in turn bound to the analyte, with one of these compounds including a magnetic nanoparticle that is then detected by the sensor. In this way, the analyte is detected by detecting the magnetic nanoparticle. By counting the number of magnetic nanoparticles, the concentration of the analyte in the test fluid can be determined.
