MAGNETIC DISK DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240096361 titled 'MAGNETIC DISK DEVICE
Simplified Explanation
The patent application describes a magnetic disk device that includes a heater to adjust the flying height of the read head, a detection portion to monitor the flying height, and a controller to adjust the power supplied to the heater based on the flying height. In case of a read error, the device detects the flying height in the error region, determines an assist amount to correct it, and re-tries reading the error region with the adjusted power value.
- Magnetic disk device with a heater to adjust the flying height of the read head

Original Abstract Submitted
according to one embodiment, a magnetic disk device includes a magnetic disk, a magnetic head including a write head, a read head, a heater which adjusts a flying height of the read head and a detection portion which detects a flying height of the read head, and a controller which controls a power value supplied to the heater in accordance with the flying height, and, when a read error occurs, detects, with the detection portion, the flying height of the read head in an error occurrence region, determines an assist amount to bring the flying height in the error occurrence region to a pre-set reference flying height, and executes re-try read of the error occurrence region while inputting a power value corresponding to the assist amount to the heater.
