摘要： A method for patterning and forming very small structures on a substrate such as a wafer. The process uses a difference in surface energy between a mask and the substrate to selectively deposit a hard mask material such as a metal onto the surface of the substrate. The mask can be formed extremely thin, such as only an atomic mono-layer thick, and can be patterned by ion beam photolithography. The pattern can, therefore, be formed with extremely high resolution. The thin mask layer can be constructed of various materials and can be constructed of perfluoropolyether diacrylate (PDA), which can be dip coated to and exposed to form a desirable positive photoresist mask layer.

摘要： A method and system for determining localized contact potential voltages and localized clearance data between a slider body and a hard disk of a hard disk drive. In embodiments of the present invention, a plurality of direct current (DC) pulses are applied between said slider body and a discreet location of the hard disk. In embodiments of the present invention, the discreet location of the hard disk comprises a portion of a data track of the hard disk. In embodiments of the present invention, a variation in the clearance of the slider body is determined when a given voltage is applied. Furthermore, a first set of DC pulses has a positive/negative bias while a second set of DC pulses has a negative/positive bias. The voltage of the sets of DC pulses is increased until a contact between the slider body and the hard disk is detected.

摘要： The head of a disk drive has write elements disposed on one protrusion pad that wears away during initial operation to permit reduced tolerances and, thus, reduced spacing between the disk and head, with the read element being disposed on a separate protrusion pad and spaced from the write element pad in the radial dimension. This prevents read element recession during cooling in the absence of write current that could otherwise occur if the read element were located on the same pad as the write head.
