摘要： A continuous-media or patterned-media disk drive with a low ratio of linear bit density in bits per inch (BPI) in the along-the-track direction to track density in tracks per inch (TPI) in the cross-track direction has a magnetoresistive read head with high cross-track spatial resolution. The read head is located between two magnetic shields, with the shields and read head formed on a side surface of the head carrier perpendicular to the carrier's disk-facing surface. The carrier is supported by the disk drive actuator with the side surface of the carrier oriented generally parallel to the data tracks. In this arrangement the high-spatial-resolution direction of the read head (the transverse direction perpendicular to the side surface on which the head is formed) is in the radial or cross-track direction.

摘要： A patterned-media perpendicular magnetic recording disk has patterned servo regions and is nanoimprinted from a master mold made using directed self-assembly of block copolymers. The disk has patterned concentric circular data tracks of discrete data islands, with the tracks having a track pitch in the radial or cross-track direction. The disk also has patterned servo sectors extending generally radially across the patterned data tracks. The servo pattern is a chevron pattern of slanted or non-radial stripes that have a stripe pitch in the cross-stripe direction substantially equal to the track pitch. As a result of the method of making the master mold, the nanoimprinted disk has a chevron servo pattern with non-radial stripes that are magnetized segments of radial lines separated by nonmagnetic spaces.

摘要： A system and method accurately clocks write data to the discrete data blocks in a patterned media disk drive. The precise time intervals between successive timing marks in the data tracks are measured by a timing mark detector that counts the integer number of write clock cycles between successive timing marks and the fractional part of a write clock cycle by detecting the phase difference between a timing mark and a reference signal. The resulting timing error is output to a write clock compensator. The write clock is capable of generating equally spaced primary phases and phases intermediate the primary phases. The compensator includes a phase rotator that controls which write clock phase is selected for output. The value in a phase register of the compensator is used to control the phase rotator to advance or retard the write clock phase, and thus to adjust its frequency and phase so as to be synchronized for writing to the data blocks.

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.
