摘要： A method of making a calibration disk for a laser based inspection tool (LIT) for inspecting planar surfaces is described. The calibration disk has a plurality of overlapping bumps forming a circular ring with a width of one bump. The circular ring of bumps forms a feature of a known width and position on a disk which can be used to adjust one or more LIT's to yield calibrated results. The ring of overlapping bumps is preferably formed by rotating a disk substrate under a stationary pulsing laser beam.

摘要： A laser based inspection tool (LIT) for inspecting planar surfaces is described. In a preferred embodiment the LIT can simultaneously inspect both planar surfaces of disks for use in disk drives. In one embodiment of the invention, a disk is moved into an inspection subcompartment between a pair of air knives which blow partially ionized air onto the planar sides of the disk to remove loose particles adhering thereto. After the disk moves through the air knife streams, the two laser beams scan the two sides of the disk. Preferably the scan occurs after the air knives have been turned off and as the disk moves out of the inspection subcompartment. The subcompartment may optionally have an air source which forces air to flow out of the subcompartment to aid in maintaining a clean environment for inspection.

摘要： A laser based inspection tool (LIT) for inspecting planar surfaces is described. In a preferred embodiment the LIT can simultaneously inspect both planar surfaces of disks for use in disk drives. The choice of a polygon scanner is preferred, but other scanning means such as a galvonometer mirror could be used. A separate polygon scanner is used for each side of the disk. The polygons are arranged in a common plane, but rotate in opposite directions to reduce the inteference which might otherwise result when the beams pass through the central hole in the disk and impinge on the detection channel for the other side. Preferably the rotation of the polygons is synchonized and angularly offset so that the two beams are synchonized and offset. The rotating polygons may conveniently be included in a system which scans each of the two laser beams through a telecentric lens assembly onto the surface and which routes the reflected light which passes back through the telecentric lens and is reflected from the polygons to the detection component.

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.

摘要： In one embodiment, a tape movement constraint for a tape drive system, comprises a tiltable tape roller bearing having a roller barrel 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. At least a portion of any air bearing between the moving tape and the barrel surface is quenched using grooves formed in the barrel surface. Other embodiments are described and claimed.
