摘要： An optical positioning circuit includes an electro-optic positioner which positions an optical beam on an optical medium to read/write patterns of data on the optical medium, and a driver circuit, such as an inductive capacitive circuit, which drives the electro-optic positioner.

摘要： A flying optical head assembly for a magneto-optical data storage device includes a slider body mounting an optical element having a narrowed optical aperture extending through a location of the slider body, a recessed region surrounding the location passing the optical aperture, a magnetic pole sheet layer for heat dissipation and reduced magnetic reluctance formed in the recessed region and having an insulation layer and an opening for the optical aperture, and a magnetic bias coil formed on the insulation layer and surrounding the narrowed optical aperture. When formed of electrically conductive material, the sheet layer includes at least one radial slot for preventing a single turn short circuit in direct proximity to the coil. Multiple slots are preferred for bonding and to reduce eddy currents.

摘要： A thin film two-pole inductive magnetic head for a computer disk drive assembly. The head comprises a substrate, a first pole formed over the substrate, a gap layer formed over the first pole and a second pole formed over the gap layer. The first and second poles have their distal ends coupled together in a yoke region, while their proximal ends terminate at their tips in an air bearing surface. A leading surface of the first pole extends back toward the yoke region at an acute angle to the air bearing surface. The head reduces the amplitude and high frequency content of secondary pulses in a readback waveform so as to ease the task of electronically isolating the main pulses for downstream processing of the read data.

摘要： A recording media design having discrete track recording structure where the trenches between tracks are filled with a soft magnetic material is provided. The soft magnetic material provides a low magnetic impedance path to the soft underlayer such that fringe fields from the write head are conducted to the soft underlayer without having a negative effect such as adjacent track erasure. A method of manufacturing the media includes a nano-imprint step and ion milling out the data layer to create the trenches. A B2O3 material allows the data layer to be ion milled out without redeposition bridging the B2O3 layer thus preventing lift off of the mask. The trenches are then filled by ion deposition with the layers of ferromagnetic material separated by an anti-ferromagnetic coupling that causes the flux to be conducted to the soft underlayer and remnant flux to rotate within the island and not into adjacent tracks.

摘要： An apparatus having a write head for writing data on to a recording medium comprises a recording disk medium and one or more ferromagnetic islands. The recording disk medium has a data layer in discrete tracks with trenches between the discrete tracks, and a soft underlayer beneath the data layer and the trenches. The one or more ferromagnetic islands are disposed in the trenches between the discrete tracks in the recording disk medium and over the soft underlayer. The one or more ferromagnetic islands comprise a first layer having a first magnetization direction and a second layer having a second magnetization direction that is different than the first magnetization direction.

摘要： A master is provided for use in a magnetic printing process. Illustratively, the master is used for printing servo patterns on a magnetic recording medium. The master includes a substrate on which a magnetic underlayer material is disposed. A second magnetic material is disposed over the magnetic underlayer material so as to form a plurality of teeth adapted for use in the magnetic printing process. The teeth may be formed in the second material by an additive or subtractive process. Further, the dimensions of the teeth may be selected to optimize use of the master in a magnetic printing process on perpendicular media.
