Magnetic disk device for controlling a sense current supplied to a magneto-resistive head based on an ambient temperature |
摘要 |
A magnetic disk device reproduces information from a magnetic disk by using a magneto-resistive head. The magnetic disk device includes a temperature detecting unit which detects an ambient temperature. A sense current control unit controls a sense current based on the ambient temperature detected by the temperature detecting unit, the sense current being supplied to the magneto-resistive head to detect a change of a resistance of the magneto-resistive head for the magnetic disk in a magnetic field.
