MAGNETIC DISK DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240321313 titled 'MAGNETIC DISK DEVICE
The abstract describes a magnetic disk device with 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. The system generates inspection data for the extracted data, obtains a seed value associated with both the inspection data and the media data, compares this seed value with the expected seed value, and evaluates the data as an error or descrambles it based on the comparison result.
- The magnetic disk device includes a read control system that extracts scrambled data from media data.
- Inspection data associated with a seed value at the time of write is generated for the extracted data.
- The system obtains a seed value associated with both the inspection data and the media data.
- A comparison is made between the obtained seed value and the expected seed value by the controller.
- The data is evaluated as an error or descrambled based on the result of the comparison.
Potential Applications: - Data storage systems - Information security systems - Data recovery services
Problems Solved: - Ensuring data integrity during read operations - Detecting and correcting errors in extracted data - Enhancing data security and reliability
Benefits: - Improved data accuracy and reliability - Enhanced data security measures - Efficient error detection and correction mechanisms
Commercial Applications: Title: Data Integrity Verification System for Magnetic Disk Devices This technology can be used in various industries such as data storage, cybersecurity, and information technology for ensuring the integrity and security of stored data. It can have significant market implications in sectors where data reliability is crucial.
Questions about the technology: 1. How does the read control system ensure the accuracy of extracted data? 2. What are the potential implications of using this technology in data recovery services?
Frequently Updated Research: Ongoing research in data storage technologies and information security systems may provide further insights into the development and optimization of similar data integrity verification systems.
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.
