摘要： A method of fabricating a master stamper/imprinter for manufacturing a patterned recording medium by nano-imprint lithography comprises steps of: (a) providing a substrate having a surface; (b) forming a layer of a hybrid resist material on the surface, the resist layer having an exposed upper surface; (c) subjecting selected areas of the exposed upper surface of the resist layer to an energy beam to form therein a latent image of a topographical pattern to be formed in the resist layer and having a correspondence to a pattern to be formed in a patterned recording medium; and (d) developing the latent image into the topographical pattern in the resist layer, wherein only those areas of the resist layer which have received an energy beam exposure dose between a positive-tone threshold dose D0p and a negative-tone threshold dose D0n are developed.

摘要： The present invention is used to form precise, optically detectable patterns on rotating members of a disk and spindle assembly of a disk drive used in data storage system. In particular, the invention employs an optical source to form optically detectable patterns on the rotating members of the disk drive. These optically detectable patterns are used to create an accurate clock track. The clock track may be used to create multiple accurate magnetic patterns on one or more disks attached to a disk and spindle assembly in a magnetic data storage system. By successively changing the radius at which the magnetic patterns are created it is then possible to create multiple magnetic patterns at successive radii with all such magnetic patterns having a precise geometric relationship to each other. Alternatively, the accurate clock pattern may stand alone as an encoder. Additionally, the present invention may also be used to form textured surfaces on a disk to control the flying characteristics of a magnetic head slider assembly. The present invention can also create textured surfaces which will serve as a resting area for the magnetic head slider assembly of a magnetic disk drive when the disk is not spinning.

摘要： Systems and methods are provided for correcting write synchronization of a magnetic storage device with respect to magnetic storage media and its corresponding writable magnetic bits, or dots. In particular, these systems and methods involve using time-shifting principles to calibrate the magnetic storage devices to correct slow drifts of reader-writer timing. It is to be appreciated that time-shifting techniques can be applied in a variety of manners. For example, the very dots on the media can be positioned in time-shifted fashion. In another example, the writing to the dots can be time-shifted.

摘要： Magnetic alignment marks are recorded on a recording surface of a magnetic hard disk to mark the location where the disk is abutted against the hub of the spindle of a multiple-disk servo-writer. The alignment marks for each recording surface may be different so as to distinguish between top and bottom disk surfaces so that when the discs are assembled onto the spindle of a disk drive they may be assembled with the proper orientation, i.e., the top surface is mounted “up.” The marks may be large, low frequency patterns that are both written and detected by non contact means other than the servo-track writer's or the disk drive's heads.

摘要： A plurality of redundant sets of servo data are recorded on a magnetic hard disk. The set meeting a predetermine criteria is employed when the hard disk is assembled into a hard disk drive. The determination of which set has the criteria may be conducted by the disk drive itself. The criteria may include a determination the set of servo data having meeting a minimum quality criteria or the fewest errors. The criteria may include a selection of a set of servo data having a specific pattern where the prerecorded sets may comprise a differing servo patterns that may be used by disk drives requiring specific servo patterns. The servo data are printed onto the hard disk by means of a stamper or mask having all the sets of servo data.

摘要： A disk drive system is described for forming and reading precise optically detectable patterns on rotating members of a disk and spindle assembly used in data storage system. In particular the invention describes a magnetic disk drive employing a laser system to form and sense optical clock patterns placed on the rotating members of the disk drive. These optically detectable patterns are used to create an accurate clock track. The clock may be used to create multiple accurate magnetic patterns on one or more disks attached to a disk and spindle assembly in a magnetic data storage system. By successively changing the radius at which the magnetic patterns are created it is then possible to create multiple magnetic patterns at successive radii with all such magnetic patterns having a precise geometric relationship to each other. Alternatively, the accurate clock pattern may stand alone as an encoder. Additionally, the laser system may also be used to form textured surfaces on a disk to control the flying characteristics of a magnetic head slider assembly. These textured surfaces may also serve as a resting area for the magnetic head slider assembly when the disk is not spinning.
