MAGNETIC DISK DEVICE AND METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18242712 titled 'MAGNETIC DISK DEVICE AND METHOD
Simplified Explanation: In a magnetic disk device, if a servo mark is not detected in a normal servo sector during a write operation, the controller stops the operation. It then reads the servo data from a short servo sector before the normal sector, resumes the write operation from the next data area.
- The controller stops a write operation if a servo mark is not detected in a normal servo sector.
- It reads the servo data from a short servo sector before the normal sector.
- The write operation is resumed from the data area following the normal servo sector.
Key Features and Innovation:
- Failure detection of servo mark in normal servo sector triggers a stop in write operation.
- Controller reads servo data from short servo sector before normal sector.
- Write operation resumes from next data area after normal servo sector.
Potential Applications: This technology can be applied in magnetic disk devices to ensure accurate writing of data by detecting and correcting errors in servo marks.
Problems Solved: This technology addresses the issue of failed detection of servo marks during write operations, ensuring data accuracy and integrity on magnetic disk devices.
Benefits:
- Improved data accuracy and integrity.
- Error detection and correction during write operations.
- Enhanced performance of magnetic disk devices.
Commercial Applications: Potential commercial applications include data storage systems, computer hard drives, and other magnetic disk devices where accurate data writing is crucial for operations.
Prior Art: Readers can explore prior research on error detection and correction mechanisms in magnetic disk devices to understand the evolution of this technology.
Frequently Updated Research: Researchers may find updated studies on error correction techniques in magnetic disk devices relevant to this technology.
Questions about Magnetic Disk Device Technology: 1. How does this technology improve data accuracy in magnetic disk devices? 2. What are the potential implications of failed servo mark detection during write operations in magnetic disk devices?
Original Abstract Submitted
According to an embodiment, upon a failure in detection of a servo mark from servo data recorded in a first normal servo sector in a write operation, a controller of a magnetic disk device stops a write operation. Then, the controller demodulates the servo data including the servo mark, for the servo data recorded in a first short servo sector being a short servo sector immediately before the first normal servo sector, and resumes the write operation from a data area immediately after the first normal servo sector.
