MAGNETIC DISK DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18243549 titled 'MAGNETIC DISK DEVICE
Simplified Explanation: The patent application describes a magnetic disk device that can extract scrambled data from media data, compare it with inspection data associated with a seed value, and descramble the data if the seed values match.
- The read control system extracts scrambled data from media data read from a medium.
- Inspection data associated with a seed value at the time of write is generated.
- Inspection data for data extracted from the media data is generated.
- The system obtains a seed value associated with both the inspection data and the media data.
- It compares this seed value with the expected seed value by the controller.
- When there is a mismatch, the data is evaluated as an error.
- When there is a match, the data extracted from the media data is descrambled using the seed value.
Key Features and Innovation:
- Extraction of scrambled data from media data.
- Generation of inspection data associated with a seed value.
- Comparison of seed values to determine data integrity.
- Descrambling of data based on matching seed values.
Potential Applications: This technology can be used in data storage devices to ensure data integrity and security.
Problems Solved: This technology addresses the issue of data corruption or tampering during data extraction from media.
Benefits:
- Enhanced data security.
- Improved data integrity.
- Efficient data extraction process.
Commercial Applications: The technology can be utilized in the development of secure data storage solutions for various industries such as finance, healthcare, and government.
Prior Art: Readers can explore prior patents related to data extraction and security in magnetic disk devices to understand the evolution of this technology.
Frequently Updated Research: Researchers are constantly working on improving data extraction and security protocols in magnetic disk devices to meet the growing demands of data storage and protection.
Questions about Magnetic Disk Device Technology: 1. How does this technology improve data security in magnetic disk devices? 2. What are the potential commercial applications of this technology in different industries?
Original Abstract Submitted
According to one embodiment, a magnetic disk device includes a read control system that extracts scrambled data from media data read from a medium and inspection data associated with a seed value at the time of write, generates inspection data for data extracted from the media data, obtains from the inspection data and inspection data extracted from the media data, a seed value associated with both, compares this seed value with the seed value expected by the controller, and evaluates, when the comparison result is a mismatch, the data as an error, whereas when match, descrambles the data extracted from the media data using the seed value.
