MAGNETIC TAPE HAVING CHARACTERIZED MAGNETIC LAYER SURFACE, MAGNETIC TAPE CARTRIDGE, AND MAGNETIC TAPE DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240105228 titled 'MAGNETIC TAPE HAVING CHARACTERIZED MAGNETIC LAYER SURFACE, MAGNETIC TAPE CARTRIDGE, AND MAGNETIC TAPE DEVICE

Simplified Explanation

The patent application describes a magnetic tape with specific characteristics in terms of C-H derived C concentration and frictional force on the surface of the magnetic layer.

  • The C-H derived C concentration calculated from C-H peak surface area ratio in C1s spectra obtained by X-ray photoelectron spectroscopy is between 45 atom % to 65 atom %.
  • The frictional force on the surface of the magnetic layer with respect to an LTO8 head, measured at a head tilt angle of 45°, is between 4 gf to 15 gf, with a standard deviation of 10 gf or less at various head tilt angles.
      1. Potential Applications

- Data storage devices - Magnetic tape drives

      1. Problems Solved

        1. Optimizing Magnetic Tape Performance for Data Storage Devices
      1. Possible Prior Art

There may be prior art related to optimizing magnetic tape properties for improved data storage performance, but specific examples are not provided in the abstract.

        1. Unanswered Questions
      1. How does the specific C concentration range impact the magnetic properties of the tape?

The abstract mentions a specific C concentration range, but it does not elaborate on how this affects the magnetic properties of the tape.

      1. What are the implications of the measured frictional force on the overall performance of the magnetic tape?

While the abstract provides specific values for the frictional force, it does not discuss how this force impacts the functionality and longevity of the magnetic tape.


Original Abstract Submitted
