DATA STORAGE DEVICE WITH SPLIT BURST SERVO PATTERN - A simplified explanation of the abstract

This abstract first appeared for US patent application 17839011 titled 'DATA STORAGE DEVICE WITH SPLIT BURST SERVO PATTERN

Simplified Explanation

The abstract describes a data storage device that includes disks, heads, and processing devices. The processing devices determine burst values based on sets of bursts and generate a position error signal (PES) to control the position of the heads.

  • The data storage device includes disks, heads, and processing devices.
  • The processing devices determine burst values based on sets of bursts.
  • The processing devices generate a position error signal (PES) based on the determined burst values.
  • The PES is used to control the position of the heads.

Potential Applications

  • This technology can be used in various data storage devices such as hard disk drives and solid-state drives.
  • It can be applied in computer systems, servers, and data centers for efficient data storage and retrieval.

Problems Solved

  • The technology solves the problem of accurately positioning the heads of a data storage device.
  • It addresses the issue of minimizing errors and improving the performance of data storage systems.

Benefits

  • The use of burst values and the PES allows for precise control of head positioning, resulting in improved data access and transfer speeds.
  • The technology enhances the reliability and efficiency of data storage devices.
  • It can lead to increased storage capacity and improved overall performance of data storage systems.


Original Abstract Submitted

Various illustrative aspects are directed to a data storage device, comprising: one or more disks; an actuating mechanism comprising one or more heads, and configured to position the one or more heads proximate to disk surfaces of the one or more disks; and one or more processing devices. The one or more processing devices are configured to: determine a first burst value based on an averaged value of a first set of one or more bursts; determine a second burst value based on an averaged value of a second set of one or more bursts; generate a position error signal (PES) based on the determined first burst value and the determined second burst value; and control a position of at least one head among the one or more heads based on the PES.
