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： The invention relates to a method for testing a magnetic disc having a plurality of tracks, and apparatus for such testing. The method includes scanning the magnetic disc along radial lines, storing a sequence of data points representing slopes of a plurality of tracks along the radial lines, operating on the stored set of points to determine a measured average slope for each track around an entire revolution of each track to establish a representative slope for each of the tracks of the plurality of tracks, taking a radial moving average to establish a sequence of data points, and comparing the curvature profile to a pre-established limit to determine suitability of the disc for use in a disc drive.

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.

摘要： A surface treatment process employing pulsed laser energy enables selective texturizing and polishing of non-magnetizable substrate disks used in fabricating magnetic reading and recording media. Substrate surfaces are texturized over dedicated head contact zones to form multiple nodules that are highly uniform to precisely control surface roughness. Laser polishing of data zones causes localized flow of the substrate material, to remove the residual scratches of mechanical polishing without altering the non-magnetic character of the substrate at large. Between the data zones and contact zones, transition zones can be formed by selectively graduating the nodule heights in the radial direction. The rounded structure of the nodules increases surface resistance to intended or incidental transducing head contact. Removal of residual scratches enhances resistance to corrosion and improves signal quality, since subsequent layers, including the thin film recording layer and the protective carbon layer, tend to replicate the substrate surface topography.
