Patent for Magnetic Head with Canted Arrays Published by IBM Corporation

Strategic Insights

— 2 min read

Researchers at International Business Machines Corporation (IBM) have developed a patent for a magnetic head with canted arrays, which aims to increase data storage density in tape storage systems. The patent, filed on May 1, 2013, and published on September 8, 2015, provides a solution to the limitations of current tape storage systems by introducing an innovative design for the magnetic head. The inventors, Robert G. Biskeborn and Calvin S. Lo, have created a magnetic head with an array of transducers that are oriented at an angle relative to the tape bearing surface, allowing for improved data storage density.

Key Takeaways:

  • The patent aims to increase data storage density in tape storage systems by reducing feature sizes of readers and writers.
  • The inventors have developed a magnetic head with an array of transducers that are oriented at an angle relative to the tape bearing surface, allowing for improved data storage density.
  • The patent provides a solution to the limitations of current tape storage systems, which are limited by the quantity of data stored on a magnetic tape due to tape dimensional instability (TDI).
  • The TDI is a result of tape lateral expansion and contraction caused by changes in humidity, tape tension, temperature, aging, etc.
  • The patent aims to improve the areal density of data storage by reducing the impact of TDI on track spacing.
  • The inventors have designed a magnetic head with a tape bearing surface having a first edge oriented perpendicular to the intended direction of tape travel.
  • The array of transducers in the magnetic head is oriented at an angle relative to the first edge, between 0.2° and 10°.
  • The patent provides a computer program product for orienting a head to achieve the desired pitch for transducers.

Statistics:

  • The patent was filed on May 1, 2015.
  • The patent was published online on September 8, 2015.
  • The patent is assigned to International Business Machines Corporation (IBM).
  • The patent has a unique identifier of 9129614.
