| 20090046547 | SYSTEM, METHOD, AND APPARATUS FOR CHARACTERIZING, TRACKING, AND SEGREGATING KNOWN DEFECTIVE DISK REGIONS ON PATTERNED DISKS - A system for tracking and segregating repeated defects on media disks as tabled data in disk drives is disclosed. The disks have the same defects as the sub-master from which they are formed. Likewise, the sub-masters have the same defects as the master from which they are formed which, in turn, are passed down to the disks themselves. This information is recorded in the disk drives to avoid read/write operations in the affected sectors of the disks. In addition, the order and production quantities of sub-masters and disks made are tracked since replication performance decays over time. | 02-19-2009 |
| 20090154017 | SYSTEM, METHOD AND APPARATUS FOR PATTERNED MEDIA WITH REDUCED MAGNETIC TRENCH MATERIAL - A bit patterned magnetic media design for reducing the amount of magnetic material located in the trenches between topographic features is disclosed. An intermediate non-magnetic layer is deposited on the topography prior to depositing the functional magnetic layer on the topographic substrate features. The non-magnetic layer increases the width of the land regions that will ultimately support the functional magnetic layer. The non-magnetic layer also reduces the amount of trench deposition that can occur in the subsequent deposition of the magnetic recording layer. By eliminating most of the magnetic trench material, the amount of magnetic flux and readback interference produced by the trench material is reduced to an acceptable level. | 06-18-2009 |

| 20100165512 | SYSTEM, METHOD AND APPARATUS FOR MASTER PATTERN GENERATION, INCLUDING SERVO PATTERNS, FOR ULTRA-HIGH DENSITY DISCRETE TRACK MEDIA USING E-BEAM AND SELF-ASSEMBLY OF BLOCK COPOLYMER MICRODOMAINS - A system, method, and apparatus for forming a high quality master pattern for patterned media, including features to support servo patterns, is disclosed. Block copolymer self-assembly is used to facilitate the formation of a track pattern with narrower tracks. E-beam lithography forms a chemical contrast pattern of concentric rings, where the spacing of the rings is equal to an integral multiple of the target track pitch. The rings include regions within each servo sector header where the rings are offset radially by a fraction of a track pitch. Self-assembly is performed to form a new ring pattern at the target track pitch on top of the chemical contrast pattern, including the radial offsets in the servo sector headers. When this pattern is transferred to disks via nanoimprinting and etching, it creates tracks separated by nonmagnetic grooves, with the grooves and tracks including the radial offset regions. | 07-01-2010 |
| 20100172048 | Servo patterns for patterned media - Servo patterns for patterned media. The servo pattern includes specification of cylinder/track ID with and without a Gray code.

The island allocation also provides for easier lift-off. Logic is used to encode and decode the Gray code. Further, the Gray code is designed to stabilize the magnetic island/non-magnetic island ratio to allow for easier manufacture. | 07-08-2010 |
| 20100320393 | OFF-AXIS ION MILLING DEVICE FOR MANUFACTURE OF MAGNETIC RECORDING MEDIA AND METHOD FOR USING THE SAME - A tool for patterning a disk such as a magnetic media disk for use in a disk drive system. The tool includes a chamber and a first and second series of magnets, each evenly spaced about the chamber wall. An ion beam source at an end of the chamber emits an ion beam toward the disk which is held within the chamber. The first series of magnets deflect the ion beam away from center and toward the chamber wall. The second ion beam source deflects the ion beam back toward the center so that the ion beam can strike the disk at an angle. In addition, to bending the ion beam, the magnets also rotate the bent ion beam so the movement of the ion beam revolves within the chamber. | 12-23-2010 |
