  • Patent number: 7268963
    Abstract: Self-servo-writing of multi-slot timing patterns is described. Individual timing marks are replaced with groups of timing mark slots. At each timing mark location, a time measurement is made by detecting a timing mark in one of the slots. Also, extensions to the existing timing marks are written in other slots. The combination of timing measurements at every timing mark and extensions to those timing marks written at every opportunity improves the overall precision of the timing propagation. The improved accuracy of timing mark placement produces a commensurate improvement in the placement of the concomitantly written servo-data. In addition, the alignment accuracy of the written pattern is less sensitive to variations in rotation speed and variations in the shape of written transitions. Moreover, only a single disk revolution is required at each servo radius to write servo data and propagate the timing marks to maintain timing alignment.

  • Patent number: 7136243
    Abstract: Improvements in placement of timing patterns in self-servowriting include correcting for systematic errors due to geometric effects. A correction is made for varying systematic errors, such as when the recording head has spatially separate read and write elements. Further, servopattern rotation due to residual or unmeasured systematic errors is reduced by using a once per revolution clock index derived from the motor drive current waveform or any other sensor. In one aspect of correcting for systematic errors in the writing of timing patterns on a storage medium of a storage device, a time interval between a trigger pattern written at a first radial position of the storage medium and a rotational index is measured. The rotational index is related to the rotational orientation of the storage medium with respect to a fixed frame of the storage device.

  • Patent number: 7016140
    Abstract: Embodiments of the present invention provide a technique to correct timing mark position error in self-servo write (SSW). In one embodiment, a method of correcting a timing mark position error of a SSW pattern of a disk drive comprises writing a plurality of timing mark bursts over a plurality of steps on a disk, the plurality of timing mark bursts including at least one misaligned burst having an intentional misalignment in a first step with respect to a corresponding burst in a neighboring second step; reading the misaligned burst and the corresponding burst at a seam between the first step and the second step to obtain a measured burst amplitude; and using the measure burst amplitude to obtain a timing mark position error, which may involve comparing the measured burst amplitude and an expected burst amplitude computed based on the intentional misalignment between the misaligned burst and the corresponding burst to obtain a timing mark position error.

  • Patent number: 6735031
    Abstract: A method for writing timing marks on a rotatable storage medium, such as on a disk in a disk drive, includes the steps of: 1) during a rotation of the disk, detecting the passage of at least a portion of a first timing mark located at a first radius of the disk, and 2) writing a second timing mark at a second radius of the disk, the location of the second timing mark being based at least in part on a stored calculation of a delay from the time of passage of the first timing mark during a rotation of the rotatable storage medium. The location of the second timing mark is calculated based on alternative time intervals between detected timing marks and on various functions of the time intervals.

  • Patent number: 6633451
    Abstract: A method is provided for writing a servo-pattern on a storage medium. According to the method, first timing marks are written at a first radial position of the storage medium, and the head is moved to a second radial position. Time intervals between selected pairs of the first timing marks are measured, and other timing marks are written at the second radial position of the storage medium. The measuring step is performed after the moving step. In one preferred method, the steps of moving, measuring, and writing other timing marks are repeated until the servo-pattern is written on an entire surface of the storage medium. A method is also provided for generating an initial aligned pattern of timing marks for self-servo-writing on a storage medium.

  • Patent number: 6429989
    Abstract: A method for writing timing marks on a rotatable storage medium, such as on a disk in a disk drive, includes the steps of: 1) during a rotation of the disk, detecting the passage of at least a portion of a first timing mark located at a radial trajectory at a first radius of the disk, and 2) during the same rotation of the disk, writing a second timing mark at a second radius of the disk. The second timing mark is located at least one of a) where at least a portion of the second timing mark overlaps at least a portion of the radial trajectory of the first timing mark, and b) where the second timing mark is in close proximity to the radial trajectory of the first timing mark. The second timing mark is written based on different parameters such as a measured time interval, a calculated time interval, and a predetermined delay.
