    Disk tilt in optical drives causes track offset, a problem not solved by standard tracking methods. This study quanties track offset, revealing its dependence on system parameters and beam segmentation for digital versatile disks.

    Area of Science:

    • Optical Engineering
    • Data Storage Technologies

    Background:

    • Disk tilt in optical disk drives introduces tracking-error signal (TES) offsets.
    • Standard TES correction methods do not fully address coma-induced track offset.

    Purpose of the Study:

    • To define and quantify track offset in optical disk drives under disk tilt conditions.
    • To analyze the impact of various system parameters on track offset.

    Main Methods:

    • Calculated track offset based on system parameters like track pitch, wavelength, and objective lens properties.
    • Evaluated track offsets for different beam-segmentation schemes in digital versatile disks (DVDs).

    Main Results:

    • Track offset is dependent on system parameters including track pitch, wavelength, and objective lens characteristics.

  • For differential phase tracking, track offset is influenced by mark length.
  • Calculations show track offset variations for different beam-segmentation strategies.

    • Conclusions:

    • Standard TES correction is insufficient to mitigate coma-induced track offset caused by disk tilt.
    • Understanding parameter dependence is crucial for minimizing track offset in optical disk systems.
    • Beam segmentation strategies significantly affect track offset in DVD systems.
