MAGNETIC DISK DEVICE AND REFRESH PROCESSING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18182693 titled 'MAGNETIC DISK DEVICE AND REFRESH PROCESSING METHOD
Simplified Explanation
The patent application describes a magnetic disk device with a control unit that can adjust a parameter (k) within different ranges during specific periods to optimize performance.
- The control unit includes an adjustment unit, a counter, a determination unit, and a refresh processing unit.
- The adjustment unit adjusts the parameter k within a first range during a first period and within a second range during a second period.
- The upper limit of the parameter k within the second range is smaller than the lower limit of the parameter k within the first range.
Potential Applications
This technology could be applied in various magnetic disk devices to improve their performance and efficiency.
Problems Solved
This innovation helps in optimizing the performance of magnetic disk devices by adjusting a key parameter based on specific ranges and periods.
Benefits

Original Abstract Submitted
According to one embodiment, a magnetic disk device includes a disk, a first head, and a control unit. The control unit includes an adjustment unit capable of adjusting k, a counter, a determination unit, and a refresh processing unit. The adjustment unit adjusts the k to a numerical value within a first range during a first period, and adjusts the k to a numerical value within a second range during a second period. The upper limit of the numerical value within the second range is smaller than a lower limit of the numerical value within the first range.
