DISK DEVICE AND HEAD STACK ASSEMBLY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18446944 titled 'DISK DEVICE AND HEAD STACK ASSEMBLY

The abstract of the patent application describes a disk device with specific features such as an arm with a through hole, a base plate, a load beam, and a damper. The device is designed to interact with a magnetic disk in a precise manner.

  • The disk device includes an arm with a through hole, a base plate, a load beam, and a damper.
  • The arm has a first surface and a second surface, while the base plate has a first protrusion in the through hole.
  • The load beam is attached to the base plate and has specific surface orientations to interact with the magnetic disk effectively.
  • The damper is attached to the load beam in a specific configuration to optimize performance.
  • The device is designed with a specific ratio between distances to ensure proper functionality.

Potential Applications: - This technology can be used in hard disk drives to improve read and write performance. - It can also be applied in data storage systems to enhance data access speed and accuracy.

Problems Solved: - The technology addresses issues related to disk device stability and performance. - It improves the overall efficiency of data storage systems.

Benefits: - Enhanced disk device performance and reliability. - Improved data access speed and accuracy. - Increased efficiency in data storage systems.

Commercial Applications: Title: Enhanced Disk Device Technology for Improved Data Storage This technology can be commercialized by manufacturers of hard disk drives and data storage systems to offer faster and more reliable storage solutions to consumers. It can also be integrated into cloud storage systems to enhance data processing capabilities.

Questions about the technology: 1. How does this disk device technology compare to traditional disk drive designs? 2. What specific advantages does the damper attachment provide in terms of disk performance and longevity?


Original Abstract Submitted

According to one embodiment, a disk device includes an arm with a through hole, a base plate, a load beam, and a damper. The arm has a first surface and a second surface opposite the first surface. The base plate has a first protrusion in the through hole. The load beam is attached to the base plate and has a fourth surface and a fifth surface opposite the fourth surface. The first surface and the fourth surface faces one magnetic disk. The fifth surface is inclined so as to be closer to the one magnetic disk as is further away from the arm. The damper is attached to the fifth surface. A value obtained by dividing a first distance between the first surface and the second surface by a second distance between an end of the damper and an axis of the through hole is 0.11 or less.
