摘要： A head stack assembly for a data recording disk drive has a carriage on which a coil is mounted. The carriage has a first surface and a second surface. A first head gimbal assembly is mounted on the first surface, and a second head gimbal assembly is mounted on the second surface. A datum member is formed on each of the surfaces of the carriage. The datum member is used to position each of the head gimbal assemblies on their respective surfaces. The datum member has two pins that engage apertures in the head gimbal assemblies. A pivot member is located in a separate aperture between the pins such that the head stack assembly is balanced at the center of the pivot member.

摘要： A method and apparatus to provide a retract circuit that can correspond to the tendency toward miniaturization and low supply voltage. When drive supply voltage Vcc is applied, a retract circuit charges a retract condenser Cr with boosted voltage Vup, equal to three times Vcc, generated by a booster circuit. Then, if the drive supply voltage Vcc is cut off and a VCM driver stops, the retract circuit detects power-off with a power OFF sense circuit, and provides retract delay time by a retract delay circuit. Furthermore, when the retract delay time elapses after the drive power supply is turned off, the retract driver switches the switching circuits on, discharges the retract condenser, charged at the boosted voltage, supplies discharge current to a voice coil, and retracts the head assembly.

摘要： A method for making a master disk for nanoimprinting patterned-media magnetic recording disks has patterns for both the data islands and the nondata regions. The method uses guided self-assembly of a block copolymer (BCP) to form patterns of generally radial lines and/or generally concentric rings as well as patterns of gap regions of one of the BCP components. The pattern of lines and/or rings have the BCP components aligned as lamellae perpendicular to the substrate, while the pattern of gap regions has the BCP components aligned as lamellae parallel to the substrate. One of the BCP components is removed, leaving the other BCP component as an etch mask to fabricate either the final master disk or two separate molds that are then used to fabricate the master disk.

摘要： A method for manufacturing a bit patterned magnetic media for magnetic data recording. The method includes selectively depositing a self assembled monolayer over a seed layer and then oxidizing the deposited self assembled monolayer. The self-assembled monolayer can be deposited by use of a stamp to form a pattern covering areas where a non-magnetic segregant (such as an oxide) is to be formed and openings where a magnetic material is to be formed. A magnetic alloy and a segregant (such as an oxide) are then co-sputtered. The magnetic alloy grows only or selectively over the seed layer, whereas the segregant grows only or selectively over the oxidized self-assembled monolayer.

摘要： A method for manufacturing a bit patterned magnetic media for magnetic data recording. The method includes patterning a topography that includes an array of raised regions separated by a recessed portion. The array can be patterned by micro-printing using a stamp that has raised islands. The raised regions can have a height of 1 to 5 nm as measured from the recessed region. A magnetic alloy and a non-magnetic segregant are then co-sputtered. The magnetic alloy preferentially grows over the raised portions and the non-magnetic segregant grow preferentially over the recessed region between the raised portions.

摘要： Methods of defining servo patterns and data patterns for forming patterned magnetic media are described. For one method, a lithographic process is performed to define a servo pattern in servo regions on a substrate. The lithographic process also defines a first data pattern in data regions of the substrate. The first data pattern is then transferred to (i.e., etched into) the data regions. Self-assembly structures are then formed on the data pattern in the data regions to define a second data pattern. The servo pattern is then transferred to the servo regions and the second data pattern is transferred to the data regions. Thus, the servo pattern is defined through lithographic processes while the data pattern is defined by a combination of lithographic processes and self-assembly.

摘要： A patterned perpendicular magnetic recording disk has a pre-patterned disk substrate with pillars and trenches arranged in data regions and servo regions. In the data regions, the height of the data pillars is equal to or greater than the spacing between the data pillars, while in the servo regions the height of the servo pillars is less than the spacing between the servo pillars. A magnetic recording material with perpendicular magnetic anisotropy is deposited over the entire disk substrate, which results in magnetic material on the tops of the data pillars and servo pillars and in the servo trenches. The material in the data trenches is either nonmagnetic or discontinuous. After the application of a high DC magnetic field in one perpendicular direction and a low DC magnetic field in the opposite direction, the resulting disk has patterned servo sectors with servo pillars all magnetized in the same perpendicular direction and servo trenches magnetized in the opposite perpendicular direction.
