==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 18498739 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 properties related to the composition and surface abrasion of the magnetic layer. 

* The magnetic tape has a C—H derived C concentration of 45 atom % to 65 atom %, calculated from C—H peak surface area ratio in C1s spectra obtained by XPS at a photoelectron take-off angle of 10 degrees.
* In an environment with a temperature of 23°C and a relative humidity of 50%, the AlFeSil abrasion value of the surface of the magnetic layer measured at a tilt angle of 45° of an AlFeSil prism is 20 μm to 50 μm.
* The standard deviation of the AlFeSil abrasion value measured at each given tilt angle of the AlFeSil prism is 30 μm or less.

== Potential Applications ==
The technology could be applied in the manufacturing of high-quality magnetic tapes for data storage, archival purposes, or magnetic recording devices.

== Problems Solved ==
This innovation addresses the challenge of maintaining consistent surface quality and composition of magnetic tapes, which is crucial for ensuring reliable data storage and playback.

== Benefits ==
The magnetic tape's specific composition and surface abrasion properties contribute to enhanced performance, durability, and longevity of the tape, leading to improved data retention and playback quality.

== Potential Commercial Applications ==
* High-density data storage solutions
* Magnetic recording devices for professional audio or video production

== Possible Prior Art ==
There may be prior art related to magnetic tape manufacturing processes, surface treatment techniques, and compositions used in magnetic storage media.

==Original Abstract Submitted==

A magnetic tape in which a C—H derived C concentration calculated from a C—H peak surface area ratio in C1s spectra obtained by XPS performed on a surface of the magnetic layer at a photoelectron take-off angle of 10 degrees is 45 atom % to 65 atom %, and in an environment with a temperature of 23° C. and a relative humidity of 50%, an AlFeSil abrasion value of the surface of the magnetic layer measured at a tilt angle of 45° of an AlFeSil prism is 20 μm to 50 μm, a standard deviation of an AlFeSil abrasion value of the surface of the magnetic layer measured at each of given tilt angles of the AlFeSil prism is 30 μm or less, and the tilt angle of the AlFeSil prism is an angle formed by a longitudinal direction of the AlFeSil prism and a width direction of the magnetic tape.
