Unanswered Questions
How does the controller determine the optimal power values for the heaters based on the resistance ratio?
The patent application mentions that the controller controls the power supplied to the heaters based on the ratio of their electric resistance values. However, it does not provide details on the specific algorithm or method used to determine the optimal power values for each heater.
What are the potential implications of adjusting the flying height of the write and read heads on the overall performance of the magnetic disk device?
While the patent application highlights the importance of adjusting the flying height of the heads for data access, it does not delve into the potential effects of these adjustments on the overall performance and reliability of the magnetic disk device. Further research or testing may be needed to fully understand these implications.
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.
