MAGNETIC DISK DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18119636 titled 'MAGNETIC DISK DEVICE
Simplified Explanation
The patent application describes a magnetic disk device with heaters to adjust the flying height of the write and read heads, controlled by a controller based on the electric resistance values of the heaters.
- Write head adjusts flying height for writing data to the magnetic disk.
- Read head adjusts flying height for reading data from the magnetic disk.
- First heater adjusts flying height of the write head.
- Second heater adjusts flying height of the read head.
- Controller controls powers supplied to the heaters based on their electric resistance values.
Potential Applications
This technology could be applied in the development of high-performance magnetic disk drives for data storage applications.
Problems Solved
This technology helps in maintaining optimal flying heights of the write and read heads, ensuring accurate reading and writing of data on the magnetic disk.
Benefits
- Improved data storage reliability. - Enhanced data transfer speeds. - Extended lifespan of the magnetic disk device.
