Unanswered Questions
How does the controller determine the power values for the heaters?
The controller calculates the power values based on the ratio of electric resistance values of the heaters.
What is the impact of the resistance ratio on the performance of the write and read heads?
The resistance ratio affects the flying height adjustment of the heads, which in turn influences the accuracy and speed of data reading and writing processes.
Original Abstract Submitted
According to one embodiment, a magnetic disk device includes a magnetic disk, a magnetic head including a write head which writes data to the magnetic disk, a read head which reads data from the magnetic disk, a first heater which adjusts a flying height of the write head, a second heater which adjusts a flying height of the read head and a controller which controls powers supplied to the first heater and the second heat, and controls a power value of the power supplied to the first heater according to a ratio between an electric resistance value of the first heater and an electric resistance value of the second heater.
