    摘要： A method for making a patterned magnetic recording disk uses patterned ion implantation of the disk substrate. Energetic ions, such as He, N or Ar ions, are directed to the disk substrate through a mask, preferably a non-contact mask. They are implanted into the substrate, and the process causes localized topographic distortions in the substrate surface. A magnetic layer is then deposited over the substrate in the conventional manner, such as by sputtering. The result is a disk with patterned magnetic regions that are raised above the substrate surface. Because these regions are elevated, they are closer to the recording head in the disk drive and can thus be individually recorded to form discrete magnetic bits. Depending on the type of substrate used, the ion implantation can cause either localized swelling to form pillars or localized compaction to form pits. The patches of magnetic material on the tops of the pillars, or on the substrate surface between the pits, form the discrete magnetic bits.

    摘要： A scanning-aperture electron microscope system and method in which a radiation source generates a radiation beam that is incident upon a surface of a sample material causing electrons to be ejected from the surface. When magnetic imaging is being performed, a polarization rotator polarization-modulates the radiation beam. A scanning-aperture probe having an aperture is positioned in proxiity to the surface of the sample material so that photoelectrons ejected from the surface of the sample material pass through the aperture. A detector detects the electrons passing through the aperture. The electron detector outputs a signal in response to the detected electrons that is used for imaging magnetic and/or spectroscopic features of the surface of the sample material. The resolution of the imaged features is about equal to a size of the aperture.

    摘要： A method of making a disc for a computer disc drive and a disc made in accordance with the same. The disc includes a deposited magnetic layer of a thin film medium over a disc-shaped substrate. A master pattern having a plurality of tracks is recorded on the disc. Each track on the disc includes a plurality of magnetic islands, each having a size and magnetic properties. The size and/or magnetic properties of one or more of the magnetic islands of each track are modulated such that each track has a modulation frequency, so as to imprint a magnetic topology on the disc. The modulation frequency of each track is either a fundamental frequency or an overtone of the fundamental frequency.
