MAGNETIC DISK DEVICE AND METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18442489 titled 'MAGNETIC DISK DEVICE AND METHOD
Simplified Explanation: The patent application describes a magnetic disk with a first area for data blocks and a second area designated for writing data from a host. The disk includes a volatile memory for receiving write data and a controller that manages the writing process to prevent data corruption.
- The controller assesses the impact of Advanced Technology Instructions (ATI) on each data block and marks certain blocks as unwritable if they reach a threshold level of ATI influence.
- Blocks that are not marked as unwritable and have free space are selected by the controller to store a copy of the write data temporarily until it is written to the designated second area.
Key Features and Innovation:
- Utilization of a volatile memory for receiving write data from a host.
- Assessment of ATI influence on data blocks to prevent data corruption.
- Temporary storage of write data in selected blocks to ensure data integrity.
Potential Applications: This technology can be applied in various storage devices such as hard drives, solid-state drives, and magnetic disks to enhance data writing processes and prevent data corruption.
Problems Solved:
- Prevents data corruption caused by Advanced Technology Instructions (ATI).
- Ensures data integrity during the writing process.
Benefits:
- Improved data writing processes.
- Enhanced data integrity and reliability.
- Prevention of data corruption.
Commercial Applications: The technology can be utilized in the development of high-performance storage devices for industries requiring secure and reliable data storage, such as data centers, cloud computing, and enterprise storage solutions.
Prior Art: Readers can explore prior research on data writing processes, data integrity in storage devices, and technologies related to preventing data corruption in storage systems.
Frequently Updated Research: Researchers may find updated studies on data storage technologies, data integrity mechanisms, and advancements in preventing data corruption in storage devices.
Questions about Magnetic Disk Technology: 1. How does the technology prevent data corruption during the writing process? 2. What are the potential implications of this technology in the data storage industry?
Original Abstract Submitted
According to an embodiment, a magnetic disk is provided with a first area including a plurality of blocks and a second area designated as a write destination by a host. The first memory is a volatile memory that receives write data received from the host. A controller estimates a degree of influence of ATI for each of the plurality of blocks, and sets a first block in which the degree of influence of ATI reaches the first threshold value and two blocks adjacent thereto to be unwritable. The controller selects one of one or more blocks which are not set to be unwritable and have free space among the plurality of blocks, and stores a copy of write data in the first memory in the selected one block at least for a period until the write data is written to the second area.
