We developed a low-energy argon-ion-milling method to create noncircular patterns, like squares, for advanced magnetic recording media. This technique enhances data storage density beyond 1 Tbit/in(2).

Area of Science:

  • Materials Science
  • Nanotechnology
  • Physics

Background:

  • Next-generation magnetic recording technologies require higher areal bit densities.
  • Bit-patterned magnetic media are crucial for exceeding current storage limits.
  • Existing patterning methods may not efficiently produce noncircular bit shapes.

Purpose of the Study:

  • To introduce a novel, self-limiting, low-energy argon-ion-milling process.
  • To enable the fabrication of noncircular device patterns, specifically squares and hexagons.
  • To facilitate the production of bit-patterned magnetic recording media with improved performance.

Main Methods:

  • Utilizing precursor arrays of uniform circular openings in poly(methyl methacrylate).
  • Defining these openings using electron beam lithography.

  • Applying a self-limiting, low-energy argon-ion-milling technique.

    • Main Results:

    • Successfully formed noncircular device patterns (squares, hexagons) from circular openings.
    • Demonstrated a self-limiting milling process.
    • The technique is suitable for fabricating bit-patterned magnetic recording media.

    Conclusions:

    • The proposed argon-ion-milling process is effective for creating noncircular patterns.
    • This method is highly relevant for next-generation magnetic recording media fabrication.
    • The technology can be used for direct prototyping or manufacturing lithography templates/masks for mass production.
